The case is 3D printed using an inkjet printer with a raspberry pi 2 attached to a 7" touch screen that just slots right in. The case is a Koch fractal which is intersected by the screen.
An audio fractal was used to colour the outside of the case.
Two ultrasonic sensors on the side of the case detect whether someone is close and a series of recorded thank you messages cycle through.
It also doubles as a theremin with the left distance sensor giving the volume and the right changing the pitch. The software was written in processing and interfaced to an arduino sending the serial data to the raspberry pi.
All the best Rob we are going to miss your creativity, enthusiasm and know how in Science.
