For this week assignment, I used the touch_pad I made in input devices week, and experimented with all sorts of visualization in processing. I'm new to processing, so I was very excited and tried a lot of different visualization, some based on the processing examples and some I wrote more or less from scratch. Below are a few examples:

Simple visualization - just checking that all the pads response.

Motion between the pads..

In this visualization and the one below, I tried to visualize all the values that I receive when touching a certain pad. The serial read looks like this: 0...7 (pad number) = 1(when the button is pressed) or 0(when the button stopped being pressed). The red fill in the visualization appears when the pad value is 1.

This is my favorite visualization so far. Each pad turns the cube to a different direction.Download code

BTW - The touchpad actually contains only 8 pads and not 9, because the attiny44 has only 8 pins available. The middle and lower middle pads are connected to the same pin. That's why when I press one of those pads the visualization shows that both pads are active…
