Sorry, but I don't have the patience required for the intricate paper folding required to assemble incredible stuff like this astoundingly tiny DS lite with working hinge. I did go so far as to print out one of Yamaha's paper-folding kits (well, I did) after our blogger Mike wrote about it. But that was the extent of my inspiration.
However, if you're the sort who likes the origami-boggling challenge of papercraft, and can chopstick up minute paper sculptures with just a toothpick, glue, scissors, and nimble fingers, check out the DIY Paper Speakers from gadget maker Princeton (for an idea of what you've let yourself in for, check out the step-by-step PDF). They have a nice retro spin to them.
Even better, they're real working PC speakers as there's a teensy 3W amp and 1W speaker, with 3.5mm audio jack and USB cable bundled in the kit. These ship this month in Japan (but of course) at 1,980 yen ($20.45) each.
