The most technologically advanced drink-coaster?

I would like to etch interesting visible patterns into CD-R or CD-RW (or whatever disk media). Sort of like those old "spirograph
" toy patterns. I would like to use a standard CD drive, etching a visible pattern with that laser. Is this even possible? How could it be possible?

Ultimately, I'd use them as rather interesting drink coasters. Or Christmas tree ornaments. Or whatever. The goal is purely visual, no data need be readable.
