New proposal

Inspired by the act of flying we have changed our proposal to using flex sensors under the arms and LEDs on the wings to express this motion. So as you lift your arm the LEDs gradually light up until the arm is lifted at a 90 degree angle, then all the LEDs will be on and begin to look like they are slowly pulsating. This gives the impression of quite a calm and relaxing feel which is what you would feel if you could really fly.

I have been delegated to making the dress with the wings on it and we both chose back as the main colour for easy viewing of the LEDs.
