I would if I had an advertising vehicle for some sort of car-ware shop (garage, sound system installs, bodyshop or the like). Then again, I could see those with some spinning Pink caps that say 'Mary Kay' on them in a moments notice too..
Or if I was just a pimp-ass gangsta, those would be FLY yo'!
Seriously that's impressive technology, to change it on the fly like that? The pics are being generated by 3 spinning neon strips? Props to the designers. Now go put that brainpower to real use by making a cure for cancer.. (lol)
