Aha! I started this one last friday from 11pm to about 4am... and it went great :) !... it features 3 little cute kinda-ninja-like characters (Dodge men) who try their best to avoid the mouse pointer... so there's no real goal except moving the mouse around and see what happens... which is pretty fun in my opinion. Notice that Dodge men are a bit limited on moves yet, ill certainly update before long. So that's it... thanks to SebbyTheFreak for his tips (especially "put INTERACTIVE FLASH on your logo...) :)
Enjoy!

EDIT: for the rough .fla of this, just look among my others deviations //... I also explain how you can set it as a desktop wallpaper in my journal
