The original photo is here is a pale imitation. The OG you’re looking for is The Rollercoaster by Anatex Enterprises (of Los Angeles, CA).
Five unique, color differentiated wires of balls out, rail-riding, gravity-driven wooden bead mayhem. Though the blue wire barely counts. Its banal path is curt and uninspired; clearly an afterthought in both design and execution. F-tier. Green and orange make the entire experience worth it though.
Hell, I made them. When I was a teenager I worked at a company called Educo that made these. The machines the old guy invented that bent the wires up were crazy.
I remember being 13 years old in the doctor’s waiting room feeling awkward for wanting to play with it as I thumbed through a boring, 11 year old Reader’s Digest.
Hot take: they intentionally put these in Grown Up places that have a lot of kids so their filthy curious hands only fuck with the shiny blocks, and not with the TV remotes and the fax machines
