Just wondering if anyone has given this a go before, I was thinking how it might end up looking really rad if done well. I've painted RC car bodies (Lexan) using the same principle, working from the inside out in layers so as to leave a complex scheme when viewed outside-in. These are airbrushed or factory painted I'm sure but you can get an idea of what's possible:
The idea of working backwards from the inside allows for some interesting use of stencils, decals, and such also. Even a generic splatter or pinstripe scheme works pretty well:
Anyone given this a shot yet? I would imagine some careful planning around thicknesses and tolerances is in order, but as long as you didnt spray it on too thick I wouldnt imagine it being too much of a worry for the PCB fitment. You would want to keep any layer-to-layer mating surfaces clean, and could maybe even work in some kind of scheme where the sides of each layer alternate or show a pattern when viewed edge-on (translucent paint would work awesome for this I think...):
Thoughts? I've got some clear cases coming in a few months and am considering trying something like this when the time comes.
