In a beautiful convergence of science and art, Bert Hickman creates these “Captured Lightning” sculptures. The patterns, called Lichtenberg Figures, are “created by carefully trapping and discharging millions of volts of electrical charge inside polished pieces of clear acrylic using an electron beam from a particle accelerator.”

Captured Lightning
Incredible!
Telegraph has an amazing photo gallery. That is where the photo above comes from.
The sculptures are available to buy from Bert Hickman’s website. There, you can also see a video of the process: Captured Lightning. Very cool stuff.
