craftgrrl | nintendo ds-disguiser ideas?

Hello all,

Sorry I haven't posted anything in a while (haven't been able to really "get my craft on" recently).

I have a question for those of you gamer-crafters out there:

I'd like to make or modify some sort of professional (read: office appropriate?) -looking nintendo DS case for my bf for christmas, since he's recently expressed concern about the fact that when he brings his DS on his commute, or into stores, he gets bad customer service and stares (we're both fresh out of college, so I guess he looks young enough that he could still be mistaken for a teenager). I've been trying to think of a way to either find a basic, less-expensive DS case and modify it to "disguise" it a bit (i.e. make it look more like an iphone or a PDA case), or to create one myself - the idea being to make his DS look a little less like a toy at first glance. I briefly thought about trying to find one that was leather, but he doesn't eat red meat for ethical/environmental reasons, so cow hides aren't exactly the best option, heh. Any suggestions of materials / things I should look for / geek-chic ways to decorate it that would be subtle enough to be incorporated into a sleeker, more grown-up-looking design?

- martin luther king, jr (his area of research)
- historical documents, esp relating to asian american history, religious history, civil rights mvt.
- star wars! esp. R2D2 and chewie. (he hates the ewoks, though, for some reason...)
- the A's
- the Ram's
- the princess bride
- rock band & rock band 2
- his Xbox 360 (...madden, halo, etc...)
- WoW (he and some of his residents last year modified his Rock Band drumset to have DIY cushioning pads featuring WoW art; however, i don't think he'd like to advertise that he plays WoW to the rest of his office)
- computer parts...of all sorts. (he worked for residential computing for two years while in college and even half-jokingly/half-seriously suggested once that ethernet cables would make a very useful wedding favor...)
- joss whedon's "firefly" series (+ the film "serenity")
- how i met your mother (mostly barney stinson and his quotes)

And so it isn't text-only:
