"Analog" in parenthesis because, although it is made up of 4 analog inputs, the only analog transition between the directions (up, right, down and left) comes from the buffering material (in this case 3cm thick squishy packing material) that absorbs and spreads the pressure from the user's pushing, creating a gradual transition between the inputs.
This Fabric Joypad does not need to be used with the drawing application seen in the video, it basically supplies you with analog outputs that sense which direction (part of the circle) pressure is being applied to.
If you are interested, the drawing application etchAsketch was written in Processing and can be downloaded from the link in STEP 8.
