Anybody ever play any WildTangent games? They download real quick and play through your browser. I just started to code in it. It let's you control DirectX through Java or a scripting language. So far I've done a crappy visualization for mediaplayer, and I changed around the screensaver tutorial so that it displays JKII screenshots!
They're simple games. Most of them are from www.wildtangent.com under the section mind candy. Some are racing games, some are puzzles. Not complicated, but quite addictive.
