Whoa these are pretty cool.
What did you use to make these?
My favourite is the third one. The release of the air pression looks awesome.
Really nice chests!
Maybe it could open from the center and split the lid in two as if the hinges were not in the back, but on the sides.
Because it's so smooth, perhaps some hint of electrical power? A slight glow from somewhere as the lid opens?
