Talismoon, the same company behind the swappable Wii slot gates
and ninja-themed replacement shells
, tinkered with Nintendo's sensor bar
design to make it more compact for travel. The resulting $24.95 Sensor Wiire requires even less space than the already-low-profile standard bar and, thanks to its retractability, packs up without leaving a frustrating tangle of thin wires.
As an added bonus, you could probably use it as a pocket-sized garrotte if you don't have any other assassination tools handy. Protect ya neck and jump past the post break for more photos of Talismoon's Sensor Wiire setup.
