Here's my work in progress. (3MB file)
An Ikea 'Detolf' glass display cabinet.
a 12" rotating turntable. It currently runs on a D battery but it can use an adapter.
This way you can place 8 steelbooks on the turntable if you don't want to show the backs.
With 4 shelves, and 4 turntables, you could present 32 steelbooks in all their glory to your jealous friends.
I admit I would like to find a way to slow the turntable a little, but I'm not unhappy with the results so far.
