Press the following keys to activate or deactivate various effects for each tile: B for brightness; C for color; F for fisheye; M for mosaic; S for size; T for turning; W for whirl. Combine any effects you want! (Personally, I like turning + whirl + color). Space changes backdrop from black to white. Press D to deactivate all effects. Press L to have all the tiles take a lap. Click on individual tiles to syncronize them. (Try the face tiles!)
