Updated!  Half puzzle and half Rubik's Cube the object is to line up numbered blocks in order.  Twelve different levels from Homer's level to 143 cubes.  Homer sounds help you along the way.  Skinable program includes 11 skins.  For beginners to genius', if anyone can beat the top level let me know and I'll add a few more.
