Whats the deal with the rabbit that keeps popping up? Is it the physics simulation's Lena?

It was preceded by the Utah Teapot. There's also the Cornell Box, for global illumination testing.
So, yeah, like Lena.
I've seen the bunny and the happy buddha the most often.
Teapotahedron, please. It's the sixth platonic solid.
