Hello all creative thinkers,

I would like to know some creative ideas for ceilings. I have a log home in construction and do not want a wood ceiling, as it seems everyone has the same idea. I want something unique like me. I have thought about ceiling metal tiles, and verigated metals...anything else come to mind? I am leaning towards drywall with a mural on the ceiling right now, but surely there are other creative ideas out there. Help!
