Great examples of painting with light by Flickr users Outabounds and Christopher Renfro, including spinning ignited steel wool.
Flickr user Outabounds has a great set of light painted photographs. Together with his friend Christopher Renfro, the two set out at night to abandoned urban locations or remote fields and paint with light. The photographs featuring sparks were created by igniting and spinning steel wool.
