waveIt is a Maya MEL script, that you can use to create any sort of objects waves (can be used to simulate people waves in football stadiums, or someone waving some kind of tapestry made of interconnected bars, or any other effect that needs objects to be animated in a wavy way). The script has a manual as well as an automatic mode. This version takes into account only Y waves, so for a full 3 axis version please feel free to contact me or edit the script on your own.

The download contains the mel script, a detailed help file and a few example files.
