### **Fantastic Anatomy** In this unique workshop, we will explore and celebrate the human body in all its beautiful complexity — and then let our imagination transform it. What does a sacrum look like? Could it become a butterfly? How do hands truly connect? Can we paint the magic of a gentle touch? What lives in our hearts? Together, we will observe the body with curiosity and appreciation, and then reimagine it through colour and fantasy. This workshop is an invitation to experience the body not only as anatomy, but as a living, poetic vessel that carries us through life. Over four classes, we will explore bones, muscles, and organs in a fresh and expressive way. Using watercolour techniques that embrace fluidity and transparency, we’ll experiment with water, stains, textures, and layering to create our own artistic vision of the body. Join me in this colourful tribute to the extraordinary vessel we inhabit — where science meets imagination, and anatomy becomes art! ✨ No previous painting experience needed. Gentle guidance provided throughout. The workshop includes **four classes**, but you’re also welcome to join individual sessions (when available). To receive the registration form and full details, please contact: 📩 **hola.berlinartclub@gmail.com** **When:** Tuesday 7 - 14 - 21 - 28 April From 6 to 7.30 PM **Where:** Friedrichshain, Berlin (You will receive the exact address by e-mail) **Price:** 85€ for the whole month (4 classes) Single class 25€ / Paypal & Bank Transfer **Material:** You will need a watercolour set + watercolour paper + brushes.

Hi! Welcome to Thought Experiments in Pubs - Berlin edition, where you get to have deep conversations with people you've never met. The topic will be education. I'll post some questions that will help guide us through the topic as a comment on the day. **Location:** [Atopia Kaffeehaus, Prenzlauer Allee 187, 10405 Berlin](https://maps.app.goo.gl/Ukuup9CTrmedrB6f9) * Please consider that the locations we visit do not charge us for our booking, so in return, please make sure to show your appreciation by buying drinks or snacks. * If you're signed up but can't make the event, please cancel so someone else can take your spot * Make sure you check the right address, there is a sister pub nearby and it's not that one ☝️ **The idea:** A chance to meet and talk at a 'deeper' level, and skip the 'small talk'. **How will it work?** We will have a set of 'Thought Experiments', short, philosophical scenarios and questions, which will be discussed in groups. The conversation will flow freely, there are no strict rules, simply share and discuss your perspectives on the given topic. The thought experiments will be posted here ahead of the event. **Who should come?** Everyone! We believe that the more perspectives, the richer the conversation. This group is not about being experts in philosophy, it is about *doing* philosophy. That is, bringing our various life experiences and lenses on the world to group discussions about the human experience, the nature of reality... etc. **Do I need to bring anything?** No! Just an open, inquisitive mind. We will do 3 rounds of discussions. After the event, I would love to hear your feedback on the session. The thought experiments we will discuss are around the theme of the day. Prompts will be posted here on the day of the event. See you soon! \- Dirk *Thought Experiments in Pubs Berlin is inspired by [Thought Experiments in Pubs London](https://www.meetup.com/thought-experiments-in-pubs/), which originated in 2023 as a social experiment to get people together to connect at a deeper level.

Bringt gute Laune, schönes Wetter und Interesse mit. Wir treffen uns je nach Tour an unterschiedlichen Orten. Am 1. April 2018 um 15 Uhr gehts los am Eingang zur Akademie der Künste am Pariser Platz neben dem Brandenburger Tor.

A small NEXUS gathering built around movement and natural conversation. **Important!** We’re moving our full event schedule to our website. 👉 For all upcoming events and details, visit: [https://nexuswerkstatt.com](https://nexuswerkstatt.com)

The "classical" bookswap is simple: * We meet in a café and put the book(s) we brought down on the tables. * We browse and discuss the books with one another while sipping coffee or hot chocolate, or eating cake. * We write our names down on any books we’d like to take home (post-its and pens provided). * At the end of the evening, negotiate any books that are contended and take a new-to-you book home! Books/happiness shared are books/happiness multiplied! A Bookswap is 10 times better than a Book Club because you can talk about ALL the books instead of just one! This is a great way to give your books a new home and make room for new books: that book you feel guilty for not having read even though it's been sitting on your bedside table for the last 5 years, the book you liked but didn't love, the book you loved so much you want everyone to read it, the book you somehow own three copies of, that book you absolutely hated even though everyone else loves it, and so on. Moreover, you will meet fellow readers, get a new book or two, and several book recommendations. We’ve often had readers experience books they wouldn't normally buy and enjoy it. GROUP EXPECTATIONS for PLEASANT SWAPPING * Please bring a book! It's not that you bring one you take one, but do try your best to bring something. * Books stay on the tables, open for sharing, until you are ready to leave so that everyone can have a look. We are notably not first come first serve. Please wait until you are leaving to bag the book. * If two or more people want the only copy of a book, negotiate. Maybe one of you reads it first and then gives it to the others. Or perhaps they have found another book instead. Or leave it to fate and toss a coin. The best part: now you have found somebody whose taste you can really admire. In any case, please don't walk away with a book with several names on it without letting the others know. These negotiations are fun and easy, so don't shy away from a book because there's already a name on it, and feel free to put your name on as many books as you find interesting. It's not that you bring one you take one; you may take as many as you can negotiate. * Political discussions with consent: make sure the people you are talking to would like to have a political discussion with you. * Please respect this space as first and foremost a community for connecting readers over their love of books and reading, stories, and narratives of all sorts. Please be respectful of tastes and opinions. * If something is bothering you, please reach out to the organizers, and we'll do our best to resolve it. * Lastly, don't expect your book back. It will find a new home. If you love it, let it go. Major LANGUAGES (and genres) of this meetup: English, German, French, Spanish, Italian; Fiction, Non-Fiction, Serious Reading, Light Fun, “classics", Krimis, Booker winners, Sci-Fi, Fantasy, Self-Help and more. You never know who can read what languages, and there's no accounting for taste. We are a delightful and international group of readers. We look forward to swapping with you!

**Instinct #20** \| Workshop with ***Lo Höckner*** for **LGBTQIA+** Free with **[registration](https://wearevillage.org/en/shop/village-instinct-workshop/w15-2026)** **Beyond Overwhelm** is a somatic, collective workshop that links embodied practice to social change. Together, participants explore how capitalist working cultures shape our nervous systems toward chronic overwhelm and isolation—and how we can cultivate embodied resistance. **Beyond Overwhelm** relates to embodied learning circles with clear links to social change, aiming to practice together and empower their members to gain agency and take action. This workshop deliberately addresses the body and practicing together as a collective political practice, accessing the collective wisdom of a group. In this workshop, we are going to explore how working cultures under capitalism are creating a sense of overwhelm in our nervous systems, and furthermore, how we can cultivate embodied resistance. The session offers tools for coming out of overwhelm as a foundation for building relational strategies and counteracting individualization; exploring why this is necessary for political agency while refraiming activism. Through body-based practices, collective inquiry and imagination, this workshop gives space to explore the participant’s lived environment and how practices of connection, care and existing otherwise could be brought into it 🔵 **Beyond Overwhelm** ist ein somatischer, kollektiver Workshop, der verkörperte Praxis mit sozialem Wandel verbindet. Gemeinsam erkunden die Teilnehmenden, wie kapitalistische Arbeitskulturen unsere Nervensysteme in Richtung chronischer Überforderung und Isolation prägen – und wie wir verkörperten Widerstand kultivieren können. **Beyond Overwhelm** ist ein somatischer, kollektiver Workshop, der Körperarbeit mit sozialem Wandel verbindet. Wir üben gemeinsam, um wieder mehr Ruhe, Klarheit und Handlungsspielraum zu gewinnen – als Basis, um gemeinsam statt allein mit Druck und Stress umzugehen. Im Workshop schauen wir darauf, wie kapitalistische Arbeitskulturen Überforderung und Daueranspannung fördern – und was uns hilft, dem etwas entgegenzusetzen. Du bekommst praktische Tools, um aus dem Overwhelm rauszukommen, in Kontakt zu bleiben und Vereinzelung zu durchbrechen. Wir sprechen auch darüber, warum das für langfristiges Engagement und politische Handlungsfähigkeit wichtig ist. Mit körperbasierten Übungen, Austausch und einfachen Reflexionsformaten übertragen wir das auf deinen Alltag: Was bringt dich aus dem Gleichgewicht – und was stärkt dich? Und wie können Verbindung, Fürsorge und gegenseitige Unterstützung darin mehr Platz bekommen?

**⚔️ Introduction to Wargaming & Painting Miniature Soldiers at The Arcane Foundry ⚔️** Join me in **The War Room at [The Arcane Foundry](https://share.google/S5i6DYJnJteHWeKtd)** for a laid-back evening of hobby talk and tabletop fun! For just **$25**, you’ll get a **3D-printed regiment of 20 high quality resin models** of your choice to paint — a **$40-$70 value if you were to buy them elsewhere!** (Please look up the price of minis, you are getting a steal). Bring your creativity, relax, and let’s make something awesome together. **Choose one from Below:** * 20 Cathayan Infantry * 20 Dwarf Warriors * 20 Wood Elf Spearmen Step into a world where strategy meets artistry — and where every painted figure tells a story of battle, honor, and imagination. Join **Daclaud** at **The Arcane Foundry** for an evening that introduces newcomers and enthusiasts alike to the timeless craft of **tabletop wargaming** and **miniature painting**. My own journey began with a fascination for fantasy — knights in armor, grim and hardened warriors, and monstrous creatures locked in epic battle. That passion led me to **Dungeons & Dragons**, where I painted my first **Basic Heroes set** and felt the spark that comes from bringing a character to life in miniature form. Not long after, I discovered **Warhammer Fantasy** and **Warhammer 40,000**, and I was hooked. The vision of vast armies clashing across the table — each unit meticulously painted, each story unfolding through dice and imagination — became my creative obsession. During this event, we’ll explore the **origins of wargaming**, from its early military simulations to the richly detailed worlds of modern tabletop battle systems. You’ll learn how to **build and customize your own armies**, paint your first figures, and experience the joy of turning strategy and storytelling into a hands-on art form. Whether you’re drawn by the lore, the hobby, or the thrill of commanding miniature legions, this introduction will open the gates to a world that has captivated hobbyists for generations. **🎨 RSVP today and join us at The Arcane Foundry — where every brushstroke and battle tells a story.**

Jimmy V's Grill & Pub in Grandview Heights. We meet in the bar in the room on the right (the cigar shop). You are responsible for your own meal/drinks.
