Andy's initial foray into macro light painting with an RGB LED.
I wanted to shoot RGB LEDs for a long time but never did, for whatever reason. As usual I used only salvaged components and worked within the confines of those limitations. Here, a 5mm diffused RGB, ribbon cable much too rigid to foster any real creativity, and some curtain backdrop I had hanging aroud. An Arduino Uno drives this with a bit of code to cycle through a designated spectrum over a set period of time.
