Backrooms_(Showing 2)_Group Watch and Socialize Event
[MOVIE DESCRIPTION BELOW]
*A strange doorway appears in the basement of a furniture showroom.*
\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~
**PLEASE SEE GROUP BIO FOR FULL FAQ. Meetup only allows a certain amount of characters when posting events from a mobile device and out FAQ is longer than that limit. A condensed version is posted below here**
\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~
First-time attendees: below are some Frequently Asked Questions about events for your consideration:
* **What is involved in this type of event? (_Group Watch & Socialize Event)**
* We typically arrive before the movie, maybe chat and catch up with folks a bit, watch the movie in the theater, then afterwards have a more extended chat with everyone who saw the movie.
* **Do I have to chat before the movie?**
* Nope! Totally understandable if you'd rather just watch first so you can have something in common to discuss afterwards.
* **Will people approach me/talk to me?**
* Not a guarantee as it depends on who is hosting, but a good host or other group members will try to at least say hi to members after the movie and may make an effort to include newer faces in the conversation in some way. Please feel free to jump into the conversation as you feel comfortable and understand this is done with good intent :) We are happy to have you!
* **How will I know who is the host or where people are gathering to talk about the movie?**
* This depends on each host, but good practice is for the host to indicate a notable item of clothing they are wearing for other members to look out for. But generally we gather in a loose circle in the theater lobby or outside the theater to talk, so if you recognize the host or other group members - that's the spot we've decided on! Just kind of depends on the feel of the group where we gather.
* **What is with posting the seat numbers?**
* A good practice we've found is to post our seat numbers when we have ordered tickets for a movie. This is just another way for members of our group to find each other as it might not be immediately obvious who is here as part of the group event: some events are at public movie theaters, after all. You are not by any means obligated to post your seat number if you do not feel comfortable doing so, just something we've found that works nicely for encouraging some socialization.
* **Will there be food?**
* General guideline: if the movie starts at 7ish pm or later, you might wanna have dinner first or plan on buying movie snacks. Restaurant kitchens tend to close around 9-10pm. We sometimes do go to restaurants after movies as a group, but moreso bars whose kitchens may or may not be open. Plus, kind of bad manners for a group to descend upon a bar when the kitchen is closing is 10 minutes lol. Bars are just convenient social places, there is zero pressure to drink but there just aren't many places open late when we may leave movies. There is potential to order or provide food for group events, but it should not be expected unless stated in the event description.
* **How do I stay in contact with the group after the movie?**
* We have another app we use for discussion because Meetup is somewhat cumbersome to use for casual conversation. The app we use is called Discord. The link is posted below:
* Link: https://discord.gg/4r7QxzmSvH

\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~
* **Can I create events as a member?**
* Initially, no but this group is open to members suggesting events or becoming part of the Event Organizers over time. We don't want to open the opportunity for everybody initially to create events because that kind of role has some responsibility towards it. There are certain permissions granted to that role that not every member should have. However, if a member has a proven track record of treating every group member with due respect, and a willingness to plan events: they can become and Event Organizer and create their own events. Please reach out to leadership if this sounds like something that would interest you.
* **Can I donate to the group?**
* Absolutely! See group bio

In-Person Event: The Answers to Depression & Anxiety
This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them.
Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation donโt just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance".
Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you.
The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life.
Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.

Bondage Photography Demonstration
**The event has been canceled.**
*Note: this is a demonstration event only, you **will not** shoot you own images. However, if you bring your camera we can test it for compatibility with the studio lights.*
Bondage elements can add an extra layer of emotion and artistry to your images. Sample images on the internet are however dominated by BDSM style shots that are often sexualized and emphasize the model being in distress. In this demonstration Rachel and I show ways to use bondage elements in an artistic way. We explore the types of accessories that work best in artistic images and the best way to photograph them.
Our model is Rachel Adams, an internationally known fetish model with many years of experience in this genre.
Psychic Development Series II - Pueo Group
Private Group. Closed to the Public
Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy.
In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected.
The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve.
I look forward to sharing and discovering with you. - Cynthia

Battle of the personal agents
Join the Columbus AI community for a special event.
**Battle of the Personal Agents** is your chance to see what people are actually building with AI agents and personal automation systems. Whether youโre running OpenClaw, Hermes, or a completely custom solution, bring your agent and show the community how it works.
Weโre interested in real-world implementations: the problems your agent solves, how you use it day-to-day, how itโs hosted and managed, how you built it, and why youโve chosen to keep using it. Live demonstrations are encouraged, so be prepared to show your code, architecture, workflows, and your agent performing real tasks.
This is less about polished presentations and more about sharing practical experience, comparing approaches, and learning from one another. If youโd like to present, please contact Chris Slee (via meetup) before the event so we can allocate enough time for everyoneโs demonstrations.
Come ready to show what youโve built, discover what others are doing, and maybe find a few ideas worth taking home.
Whether youโre deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.

Claude Code with Unity
A session on using Claude Code, Anthropic's AI coding agent, in real Unity development. We'll cover what coding agents are, where Claude Code fits, and how to apply it to an actual game project.
The format is presentation-style, with live demos and time for questions throughout. After brief scene-setting on coding agents and what makes Claude Code distinct, we'll go problem-driven: demoing it live on a released Unity game and introducing each feature as a solution to a problem we hit.
What to Expect:
* An intro to coding agents and where Claude Code fits
* A live demo on a real Unity project
* Key features as solutions to real problems: ๐ข๐ซ๐ ๐ด๐ฃ๐ค.๐๐ฝ, context management, hooks, skills, subagents, and MCP
* Unity-specific pain points, including Domain Reload and MCP caveats
* Putting it together
All experience levels welcome. Food and drinks provided.
*Note: meetup topics may change โ check back for the latest details.*
