Jackson Pollock had his paint splatters. Auguste Rodin had his bronzes. Todd Johnson has a 5-million-volt particle accelerator.
Johnson creates works of art by sending pieces of acrylic through a bombardment of electron beams. The electrons get trapped inside.
A tap with a sharp, insulated tool sets them free, and they melt elaborate branching patterns into the acrylic slabs. These lightning displays are known as Lichtenberg figures.
