This customizable marble roller coaster will be open all weekend for Penguicon attendees to tinker with. It serves as a metaphor for the open source development process. We used to have a giant room-sized version of the contraption, at great expense, but in 2008 Penguicon got one of its very own. Each year, we plan to purchase additional Chaos Toy kits until one day we will match the size of the one which, in the past, was shipped in boxes to Penguicon from across the country. This popular attraction will live right here in Michigan and be available for your use every year!
