You certainly can.

It is nothing special, just a bash script that strings all the needed commands together. It is actually kind of crude but it works very well for me, and the end product is great.

The water effect is a part of XGL, Crt+Windows key and then clicking or dragging the mouse crates the efect.

With credit to you, of course
Hmmm... It doesn't seem to work for me. I have a British keyboard..

Wow - thanks for that.. Many shortcuts I didn't know about
