Megan likes Set and is disturbingly good at it. She taught me how to play on a camping trip and subsequently beat us all at it.
While travelling on vacation, I wanted to send a little present, so I wrote an implementation of Set while riding between cities in Spain and France (Barcelona, Marseille, Nice, Lyon, and Paris). I finished in Paris and sent it home.
I wrote it quickly and only know that it works in WebKit (Chrome and Safari). You can see the source here. I need to fix some of the shapes and colors and things, but I was doing it from memory. Apache 2 license applies, etc, etc.
Enjoy!
