A few months back, I featured the Pyp-Bomb - a cute-looking guitar amp built into a section of toilet down-pipe. Now Gizmodo is linking to Acoustical Art, who build high (and low) end hi-fi speakers in... toilet down-pipes. $2499 (!) gets you a big floor-standing three-way thing (with a very cool bass reflex pipe), or $150 gets you the little units pictured above, with a 3 inch speaker, available in white, black, red, yellow and grey.
