Epyx, nice to meet another Shpongle fan. 

  And 1200 mics is awesome.  Heck, anything with either Simon Posford or Raja Ram is awesome!
Ryglore, thank you, now I know who made this awesome artwork!  They're very talented.
I wired things up (sorta) using the gutted remains of my older 2 player controller.  This is why the wiring is a little messy and some of the connections don't reach.  As a result, a couple of the buttons aren't hooked up.  Also, the underside of the top panel is a bit rough.  Originally I intended to laminate it, but since that meant the T-molding wouldn't be flush, I opted for a couple quick coats of paint instead.  Since it's hidden, I don't really worry about it.

And this thing is 
awesome for Street Fighter IV.  I'm very glad I made it as no longer do I wind up with cramping fingers after a marathon SF IV session:

 Overall, I'm very happy with how this turned out.  Much better than my previous attempt at a controller.  The laminate especially gives the bottom a very nice, professional look.  Much better than paint.
Thanks again to everyone for all the great comments!
