Chris Walker dropped out of Dartmouth and became a Thiel Fellow in 2013. He had an idea for a math video game that was inspired by the TI 84 graphing calculator. He tried creating an educational video game studio but it didn't work out. He joined Hack Club, a studentled educational intiative that started teaching coding but has branched out. Hack Club's founder, Zach Latta, was also a Thiel Fellow.

Chris started Castle Bravo as a personal project with the idea of turning a bouncy castle into a boat a motorized floating bouncy castle. He's now working with young people to create a solarpowered version. Chris will bring the current version to Maker Faire Bay Area
