Here's something I'd expect to see whipped up by MAKE Magazine on Martha Stewart: A paper speaker kit that comes with all the paste and paper you need to fold together your own mini ghetto-blaster. Seriously.
The Princeton PSP-NXT speaker unit series resonates sound throughout the paper and the surface you've placed it on. In this way, each surface you try—from a desk to a glass window—becomes a "speaker box" with unique characteristics.
The kits are USB-powered, and there are three nostalgic designs to choose from: Ghetto Blaster, Hi-Fi, and old-school record player cabinet. You can also create your own designs, if, you know, you're not busy making an origami Millennium Falcon or something. [Princeton via Akihabara News]
