RedPower 2 Frames: "Linear Loop" - Simple, Editable, Expandable

Today I quickly show off a cool little device I've made using RedPower2 frames. This machine loops through a simple linear motion that can be easily expanded and edited. Just a few things I forgot to mention: I used a few cover strips to stop things interacting that shouldn't be. Some of the frames have covers to stop them interacting with the wiring.
