I had been making lightboxes for my Animation Workshop class the cheap/generic way, by takingregular old plastic lightboxes and slapping a plastic pegbar on them. Truthfully, this method is perfectly adequate for what we do in the class, and the results have been great.
However, I am always keeping an eye out for used equipment (read: cheap), and recently came across a very cheap rotating animation disc (Cartoon Colour Co.) on eBay. I ended up being the only bidder. It is, of course, a remarkable sign of the times that this type of once highly sought after (and very expensive) piece of equipment would go for so cheap given that it is practically obsolete in the industry (my guess would be that the only place that typical discs/lightboxes are still prevalent would be in colleges where it would simply be too expensive to fill entire labs with Cintiqs or variations of it).
My extremely talented carpenter father helped build the wooden, adjustable base, cut a round hole in the middle, and voila. It is underlit with a thin board with LED strips, which works perfectly. It's a beauty and will be an awesome addition to the AW.
