Creating a 3D Crystal Etching in Blender

A little while ago I decided I wanted to try creating those nifty crystal etches you find in those tourist stores. Turns out its surprisingly easy to make them in Blender. I made a 3D crystal of Suzanne.

I also made a tutorial on how to make it.

I posted the video to /r/blender and the user /u/giesse made a video showing an alternative way to put each bubble on a vertex. His technique seems to be more efficient than mine but it does add a stray bubble in the center of the etching. However, the bubbles are so small that its hard to notice it. I like his way better.
