Can engrave mirrors too!

Well you actually engrave the back of the mirror. The coating gets burned away leaving the glass exposed to varying levels. The result is stunning, especially when illuminated from the back. I plan on making a much larger (12″x12″) version on the Terminator and mounting it in a shadow frame with lighting in the back. But it will take about 9 hours to engrave it so I need to carve out a day for that.
