Yes! A challenge!!!
I certainly don't want it to just sit underneath. To me, that would be downright awful.
I've been making some templates for myself, and looking at my spare case, trying to figgure out how to do this. If I use plexiglass, I would have to fit it just perfectly. I'd probably end up wasting a few square feet before I got it right
Layser, I'm honored I could be the first to use your case as an example. I'm supprised though. With such a nice case, I'm supprised nobody's tried something similar (They're probably just too afraid)
However, I don't plan on copying you. My theme is "technological flames", so the curved and jagged points you have are exactly what I'm going to face.
I could heat the plexiglass to form it into shape... but I'm concerned about fingerprints or something else forming impressions.
Or, I could make molds of each hole and then use meltable beads from a craft shop. I've never seen this used in a case mod before, but it seems like it should work.
