With support from University of Washington Center for Game Science, DARPA, Gates Foundation, NSF, Adobe, Microsoft and Intel, Refraction was created to teach fractions. According to the website, "In Refraction, the player must partition lasers in order to power
spaceships containing various animals who have gotten stuck in space, as
shown in the picture. These animal spaceships all require different
fractions of the lasers, and the player is given several pieces that
split and bend the lasers to reach the animals and satisfy these
requirements". Refraction won the Best in Show Award in the 2010 Learning Challenge, which was sponsored by Disney Research. Below is a description of the program.
