Giant Light-Painted Rainbows Used as Group Portrait Backgrounds

At the Bring to Light nighttime art festival in NYC last weekend, artists Sean McIntyre and Reid Bingham showed off the Rainbow Tracer — a programmable rotating bar of LEDs that paints giant rainbows into the backgrounds of group portraits.

Find out more about the creation of the project here and here. All of the portraits they shot at the festival can be found in this Flickr set.
