    Oh yeah you can see the different textures on a CD that has written data, but it’s likely they’re using them as mirrors and I think that’s clever

      It’s impossible to use CDs as mirrors. This is due to bright lasers used for burning. Wait – actually it can be done, but only with pressed CDs, not CD-Rs.
