Here is 3D picture of what you could do
The Frame: 30"x36"x72"
Frame + Back, top/bottom + right side in wood (melamine):
The Front + left side : Can be Cheap Lucite (Plexiglass 0.080 inch)
What I was thinking, is doing a "slot" in the front top and put a
sliding plexiglass windows inside and get some pvc screen outside
of the front. That way YOU control how much you open it.
sorry about cheap color, I did that fast.
