I made 1/10th scale models of the machines themselves, complete with a computer inside and the blinkenlights, just because I was so struck by the design.
I just made a few for myself. Happy to send files to whomever wants to do the same. Warning--it'll be a bit of a project if you want something fully functional, not just the plastic case. Holler a reply here if you're interested and we can work out a way to privately send contact info.
Tamiko Thiel herself is selling CM T-shirts on spreadshirt. It is my understanding that the original TMC T-shirts also had print on the back, the spreadshirt ones only have the cube of brainy cubes design on the front.
