What does Mr. Tushman have on his desk?

Auggie is attracted to multiple items on Mr. Tushman's desk; a floating globe, a Rubik's-type cube made with little mirrors, drawings and paintings.

I was looking around at all the things on his desk. Cool stuff, like a globe that floated in the air and a Rubik's-type cube made with little mirrors. I liked his office a lot. I liked that there were all these neat little drawings and paintings by students on the walls, framed like they were important.
