Yep, it was not a normal use for corrugated tin, but it's no maintenance and creates a great backdrop with which to play with beams of light emanating from the 12" mirror ball I installed.
The mirror ball throws beams all the way across two back yards...onto the storage shed 40' away.
The only light source for it is a 20 watt 12 degree halogen bulb on a low voltage transformer.

Never settle for a puny 8" mirror ball. Go for it. Incredible.
