What can I say? I like what I like!
These are known as lightning sculpture, using a well known effect called the Lichtenberg figure. Marks which are left by branching electric discharges on material surfaces.
These sculptures are created by injecting a block of polished acrylic with a beam of high speed electrons from a 5 million electron volt (MeV) particle accelerator. (click HERE for a Hi def view of the picture on the right). They also do shrunken coins for … some reason. I only put a link here simply because the website was clearly designed in 1995.
So these sculptures don’t capture lightning in the strict sense, it just captures the remnants of a discharge and then the acrylic is lit up to simulate it’s effects. Still, it grabs your attention though.
Here’s a video to see how they are made.
