Moms and dads, pay attention: give the iPad with this app running to a little kid - he/she will enjoy touching the screen thus influencing the animation.
I have tested it on my 2yo kid :) and he loves playing with it.
It doubles up as a really large flashlight with the choice of thousands of colors.
This is also a fun animation app to run while the iPad is charging.
See high-res video of the older version (1.1): http://www.youtube.com/watch?v=9HDR604cfeA
When using Mood Lamp while charging in the dock, you can also turn on the date & time display, displayed in large fonts thus easily readable across the room.
