okay.... so i hope no one has done this one... i take it everyone knows what a tesla coil is, right? okay, so my basic electronics teacher in high school ran some capacitors together, used two nails, and basically did a mini version of lightning. my idea, is to do something similar to this, in a contained environment, behind a window. back lighting, of dim light, with the charges randomly going at odd times lighting it up. just gotta make sure i test it, have a good ground, and make sure of no ESD.
