Working dynamics is as cool as it looks when completed not always when you find out the gremlins in maya are not that helpful. Well After the work with rigid bodies and particles, i moved to soft body. Since i have always like to work with Cinema4d I was inspired by an awesome dude who made a 3D Tetris. i thought to try it with maya. Here is his website, he's got tons of awesome stuffs as well i will recommend.
