Thanks everyone!
I was showing my dh the light table in the SU catty and he said he would make me one (yippee!!) -- so I thought I'd share his idea with you too

He's going to get a clear or opague storage container and fix a floresent bar light (meant to hang under shelves) onto the lid. Then by placing the container on top, it SHOULD work the same way. We just need to find a container with a totally flat bottom.
The window is a good idea in the mean time
