Strange vintage plant stand

I found this plant stand at the thrift store, and I'm not sure I've ever ran across one before. It's gold metal with  swirly plastic grey and black shelves

On the shelves there are circles with little holes that (I think) are so the plants can drain? Anyway, it was a great deal, and I just had to have it. I can think of lots of places to use it, bathroom, porch, deck, etc. Anyone else seen one before?
