More information about the supposed filters that Comcast has implemented to curb Bittorrent traffic on its network. Only now it looks as though the appplication suit Lotus Notes is affected. Last week, we reported on mounting evidence that Comcast is targeting and disrupting BitTorrent traffic on its network.

We're pretty sure that he meant "boombox", but regardless, this funky little hack from music enthusiast Gregor Dauth will be making him a lot of new friends at the next break-dancing competition. For this feat of audiophile-DIY, Dauth gutted an old Grundig tape machine, added four 150-watt speakers, installed an amp he purchased on eBay, and flashed it all up with some blue fiber-optic lighting.
