Some crazy brony who works at a machining center sent this one in. Apparently he popped one of megasweets simple pony vector's into his Gibbscam program and produced this with it. He's doesn't yet have permission to actually plug it into the machine to make an aluminum rainbow dash (yet), but it's still pretty neat to watch the program in action!
Also some Filly guitar speedpainting! Art queue's are fun.
