Kiba is a dock program for Linux and Unix derivatives running GNOME. Akamaru physics engine makes it seem as if your icons have weight and shape. You can play with the icons & bounce them around your screen.
"Akamaru is a simple, but fun, physics engine prototype. It's named after the super awesome ninja dog, Akamaru, from the Naruto anime and based on the article Advanced Character Physics by Thomas Jakobsen on Verlet integration." - Kristian Høgsberg, Creator of Akamaru & Kiba dock
