Mechanical Computer: Pulley Logic Gates

Computers are incredibly complex machines that can seem daunting at first to understand. The goal of the mechanical computer project is to abstractify these complex ideas into tangible easy to understand physical models, and to educate people so that the technology behind computers seems a little less like witchcraft, and a little more like an achievable machine.

The first part of this project, Pulley Logic Gates, is directly inspired by [this awesome video](https://vimeo.com/93042377) which is the first I had heard of the idea at least. The premise seems simple enough, using 3 rings as 2 outputs and one input, we should be able to simulate logic gates utilizing weights attached via string as the "computer."

The assembled model will consist of a stand, a backboard, exactly 21 snap in hooks, 3 rings, and 4 weights of varying sizes. This model is fully printable, with the only obvious exception being some string for the pulleys to function.
