I'm not sure exactly what's going on here, but...

(Don't worry about the space, I've got permission)
Anywhoo, I've got a friend in Japan who doesn't do English well. None the less, we trade infomation at times (and, occasionally, products). Of minor interest to me (and an almost obsession to him) is the Nintendo "Hard Numbers" (like the NES-001 or DOL-101).
Anywhoo, he sent me this picture and we're guessing it's possibly NTR-101 since the DS Lite is USG-001 (what the heck USG is, we haven't a clue)...
Anywhoo, apparently, these are custom, button-less DSes (DSii?) were custom built for the Shigureden Exhibit in Kyoto. I'm not sure I quite get it, but apparently its a kind of exhibit for some 100-ish historical Japanese poems. The exhibit is primarily funded by Nintendo.
Anyway, it's kinda neat...
