Super late – My apologies
The first idea I have is for a TRON motorcycle. I like my motorcycle and would like to add EL tape and wire as well as LED’s to it. I could wire it up so that the lights would change depending on the RPM or MPH of the bike as well as other user inputs. To go along with that I would like to add EL tape and wire to my gear to complement the aesthetic. I could wire up lights on the jacket to flash with turn signals and brake lights for added safety as well as wow factor.
The next idea is a spinning LED ball. The idea is that there is a lattice of LEDs that spin along an axis. That entire armature then also spins around another axis perpendicular to the original axis. By varying the speed of the rotations and flashing the LEDs, you can create some very cool effects.
Finally I could do a silhouette shadow installation like Jim Campbell. It could see the people viewing it and replicate their shadows on the installation.
