The module version of "Ghosts of a Chance" was available at the Smithsonian American Art Museum from October, 2008 through October, 2010. Over 3,000 people completed the multimedia scavenger hunt, deciphering codes, following treasure maps, sending text messages, and uncovering hidden objects. For more information on the game, please contact Georgina Goodlander at GoodlanderG[at]si.edu.
The team that created "Ghosts of a Chance" launched an ambitious new game called "Pheon" in October 2010. Like GOAC, there is both an online and a module component to the game. Take a look, and have fun!
