Nothing on here is hot glued or slapped together. The screen is vaccu-formed to give it that old-timey bulbous look. The outer wood frame is custom built, painted, and wet-sanded to give it that gloss. The inner brass frame was laser cut. All the bits and pieces come from old machines and fittings. Nothing came from Home Depot. Some of the hoses and valves came from a 1902 boiler we just removed from our basement. Everything is made to fit and screwed or bolted in place. We were going for a grown up version of those old activity centers for toddlers- lots of levers and knobs and toggles to mess around with. Also, it still fully functions as an Etch-A-Sketch. Circles, however, are still a pain in the ass.
