Everybody wants a pinball machine of their own, but the problem is that those suckers tend to be pretty expensive. There's a way around that though, if you're determined enough; build your own out of K'Nex. The results can be pretty awesome.
This particular K'Nex pinball machine was built by instructables user Alocke, and the impressiveness of it lies not so much in the board itself, but the crazy lifts that ferry the balls around should they wind up in one of the machines several holes. It's definitely one of the coolest K'Nex pinball machines I've ever seen, and I'd love to get a chance to play with it. Not enough to bother trying to build one myself though. [Instructables]
