Had a chat with Norm and I've changed my project a little. Adding an interactive element is easier said then done and so I'll be making one prototype of the 4 elements. I think to try to make all 4 right now is a little over ambitious. I decided to start with the element of fire. So I bought a few small sheets of acrylic and made a few 'flames' by just using sandpaper to scratch the surface. I have the sequence for the lights made using processing and arduino - just tweaking to do there. I will be adding a heat sensor which the participant will activate via a small butane torch, yes Dave, I said torch! The hard part is getting the heat sensor added in which will activate the light sequence and this is a processing bit that I don't look forward to. Wish me luck!
Here is a short video of the very rough prototype. Using the flat leds works well, but I'll probably need a strip of them instead.
