When Wired posted its list of "The World's Most Annoying Technologies" a few weeks back, "The Most Useless Machine" (a box with a toggle switch, which, when flipped, causes a mechanical nubbin to emerge from inside the box, flip the switch back, then retreat back inside the box) didn't even get an honorable mention.

Perhaps by adding more toggle switches, and attaching the machine's toggle-flipping appendage to the sliding track of a printer's ink-cartridge rail, the "Useless Machine Advanced Edition" will earn a place among 2013's most irritating tech.
