This year the 5K contest has gathered 366 contestants, and you are the judge of which one is the best.
This years contest opened the contest for Flash content, and there is a lot of neat Flash contest entries, all of which are 5 KB or less.
I haven’t had the time to look through all the contestants, but a couple that seems to get good ratings (out of the Flash content) are:
Animation Box – a drawing and animation tool made in Flash MX
Remote control tank battle – two player game
