These two grates are a commission for an apartment building in Texas. Both are made from recycled/reused components (other than the steel for the frame). Both grates have kinetic elements that spin, turn or bobble.
I love adding moving parts to fences, gates and grates to give them a more dynamic and interactive presence.
