I'm always looking for real-world sources of inspiration for gaming.
I came across this video awhile ago and think it to be pretty cool.
Perhaps the things depicted are the ancient works of crabmen, before they lost their technological dominance. Perhaps they are a form of golem created by a mad wizard imprisoned on a desert island. Perhaps they are the living skeletons of creatures no longer known to the world.
Who knows? Go check out this video.
