We will be hosting a real life meetup for the 48 hour game challenge known as the Ludum Dare! It starts with giving a theme for the challenge on Friday around seven. From there, we will create a game using the theme.
There are two variants of the competition: the Competition, where one person builds a video game in 48 hours, and the Jam, where either a person or a team builds a game in up to 72 hours. We will be going over the rules and logistics on Friday in preparation for the theme release.
For more details and rules, visit the official website (http://ludumdare.com/compo/). They have a lot of past competitions and post mortems on the games built, so it's a great place to check out.
