Just quickly, here are some photos of the Thing doing its thing after dark.
A camera in its "head" lets you do light painting by running around in the skate park with a head torch on (or waving your phone/lighter etc) whilst turning dials, pressing buttons, pedaling like fury all feed in to the mix, distorting and re-colouring the light paintings or adding generating new visuals to go along side the light painting.
I have video too...but it still needs a bit of an edit before its worth looking at.
