I was just thinking ... why couldn't you use a picture frame? Just cut a bottom from balsa wood at slightly larger than the size of the inside glass, then use narrow width and about six inch heigth moulding strips and little 'L' brackets. Put it all together with brad nails or small screws after appling some elmer's glue around the edge. Drill a hole for the plug to go through the bottom box and insert a inexpensive floresent light. You could even use the picture hanger hardware as a way to hang it up in your room to store it. I am thinking screws would be best in case you had to replace the floresent lamp bulb.
