Picked this little gem up at a garage sale this summer when visiting my folks in northern Michigan (I knew they were still good for something )
It's an Evergleam™ rotating treestand. Those holes in it hold filters (red, yellow, green, blue) and the stand shines a light up through them from 3 sockets. the top and center rotate slowly, bringing different parts of your aluminum christmas tree over the different colors.
It had all 4 glass filters, but someone tossed something in the box and the yellow filter shattered. I was thinking about seeing if someone on eBay wanted this vintage piece (for a price) but with the yellow filter shattered, probably not so much.
My new thought is to build a new cauldron for my witch that would fit this and use it as the mechanism to move here stirrer sticky thing.
