Made this last summer, thought this would be a great place to post it!

My Ampeg 4x10 bass cabinet; done with normal spraypaint. I made measurements of the grille and the sprite, popped the grille off, laid painters tape down over the whole thing, drew a grid on, carefully cut out the pixels to be painted with a razor, and sprayed away.
Actually, I still have some crappy progress shots taken with my old phone...







And finally -

On a somewhat relating note - for those interested, I'm currently doing a one-man-band death metal project based on Starcraft...
Cheers!
