I'll have a bunch of Hot Toys Terminators as well as 1:1 Endobusts, T-1000 claw, etc. to display. Rather than have a plain wall behind the shelves, I'd like to have something interesting. I've been searching for things to use and/or build without success. I want it to be a little bit 3D, not flat paper, but nothing that sticks out more than .5 - 1". Any ideas, examples, or direction? Thanks for any/all help in advance.
