Lichtenberg figures (captured lightning) are the result of discharging millions of volts into an acrylic block all within in a fraction of a second.
These little blocks have always inspired me and decided to get myself one, however its just a block... It needs a case and nothing less than custom will do!
For those looking to buy a block of your own you can purchase these blocks from www.capturedlightning.com
The original blog shows you step by step how I made the display and make it USB powered!
