Just for jollies, I had looked at a couple of sites with these vinyl “skins” last year. The Inzane Skins may have been one. Another is Skin Your Skunk, which has some interesting designs also. The latter will do a skin for left hand guitars/basses if you send an email after ordering that you want the image flipped horizontally. I see that the Inzane Skins will also accommodate for lefty models, so they get my “Lefty Seal of Approval,” as far as that goes. 
There’s also a thread on doing a similar effect with custom vinyl prints.
I came to the conclusion that I’d probably just mod a bass with the pickguard, knobs, and perhaps some stickers for the fretboard (Neck Illusions, for one). But I’m not too sure about that last item.
Edited to add: for Skin Your Skunk, you receive the vinyl skin and apply it yourself. It seems to be the same for Inzane Skins, but I don’t know if they have a service where you send your guitar in, as @Whylee mentioned for his friend. Maybe for some type of custom work?
