My husband set up purple LED lights on my daughter's bed frame yesterday (you can see the conical shape at the ends of my arcs). Playing with ICM. Don't really know if it's light painting too as I moved the camera and not the light. It's all getting confusing up in here! But fun either way!
Great color and mysterious pattern. I don't know why this would work, but I turned my laptop on it's side and liked this a little better as a vertical.
