Cato uses a Dremel tool to engrave glass -- and it's much simpler than I thought. He takes you through step by step on creating a picture on a flat pane of glass. Although he creates detailed, gorgeous pictures of birds, you can use the same techniques for simpler stuff.

This is not a Hollywood production, but if you ever had an urge to engrave your name or house number on your front door window, this is for you.
