Laser-engraved glass vase, as a steampunk souvenir of Nikola Tesla's Wardenclyffe Tower (look it up, it's pretty interesting).This is raster glass engraving by laser. It was originally drawn to fit Ikea's cheap and cheerful flat-sided tank vases, so you don't even need a rotary adapter. You could put it onto anything though. Corel and PDF files included. Original artwork for this is a Blender model by Leo Blanchette http://www.clipartillustration.com/15026/wardenclyffe-tower-magnifying-transmitter-progress/ That's a pretty impressive piece of work!
