my version of a Hoberman wheel

my ultimate goal is to make an expanding mobile. but first I have to figure out the expanding part. My inspiration for this is the hoberman sphere toy. 

I took the left over styrene from my summer classes, and cut out rectangles.  Then I started putting them together.

So far so good.

There are 30 X pairs.. I may have made this one too big, cause it can stretch longer than my arms length.

One of my classmates decided to make a coral around my chair. I think he tried to trap me in it.
