ok
long long time ago. I bought this thing. Actually 2 of them.
it was made of metal wire(little thinner then coat hanger)
It was a puzzle. a mechanical one. Every thing was attached to every thing.
And there was a ring stuck in it. Ring was NOT attached to any thing.
also every thing was move able.
So by making certain angles of attached pieces, you were able to make ring move a little.
Solving the puzzle would be taking the ring out.
F-en surprising thing guy on foot was selling them. I wish i see such a thing again. I want to record that dude making them.
