Also, Frog Fractions has an IGF entry page now!
(So does Winter Vacation Story, while I'm at it.)
Box quote time! These are all things that people who are not me said about Frog Fractions:
"Ever thought it'd be cool to make a game where the content is 90% secrets?"
"It's like 'Look Around You' the video game."
"When Twinbeard set out to subvert the government using video games, there are few who would have expected him to do so through an educational game about fractions; fewer still would have expected it to work."
"Frog Fractions is the first game I've played all the way through in years."
"No spoilers, but I am incredibly excited to see this game come out."
"This is mankind's greatest achievement."
