This box controls 2DP with its two shiny knobs. One sets the speed of the X playback and the other sets the Y playback. It also has a button to change the grid being played and a slider to control the transparency of the shutter mask, and it all runs though bluetooth so no need for wires. I should have a demonstration video up soon as well as a bit more information about how I put it together.
