This rox big time. It's an official London Underground Pencil case or flat tin, that someone has added an MP3 player kit to. "The hole around Hyde Park Corner Station is where the on-off switch protrudes from the battery box."
Mchaceortiz made this and said: "This is the open view of our Make Daisy MP3 Player Kit completed in our special enclosure. The box contains 3 AAA batteries fixed with double-sided tape to the top of the box. The on-off switch protrudes through a specially-drilled hole in the to of the case."
I've shamelessly adapted the opening quote from the guys and gals at the Make blog who said: "When a son or daughter asks for a new MP3 player, you can always chime in, "In my day we built our own MP3 players - soldering both ways, uphill!"
Thanks to Matthew K for giving me the heads up on this.
