I'm in the beginning stages of drafting out ideas for building a light canopy/hood for my two enclosures, one is a ZooMed 12x12x18 and the other is an ExoTerra 18x18x24. I would like to build these out of wood and would also like to use them to cover the entire top of each enclosure, similar to canopies/hoods over aquariums.

Have any of you done anything like this? I am really interested in learning how others have made theirs.

Thank you!

Also, bonus points for pictures!
