The Chocolate Bar
Chocolate lovers will probably get more out of this candy bar mouse than gamers. Much like the LEGO mouse, this peripheral simply seems annoying to grip onto, and it would seem to be designed as a conversation piece. Oh sure, the chocolate mouse has its usefulness: two mouse buttons and an M&M-style wheel planted between two chocolate squares pretty much covers the basics.
Although the device isn't in stock, the Choco Mouse retails for around $30 and measures 9.5 x 5.5 x 2.0 cm. A wireless version is also located here, offering a creamy center sandwiched between two chocolate layers. Both devices are compatible with Windows XP, Vista, and Mac operating systems. Thanks to its thicker design, users might have better luck gripping the latter device over the thinner model.
While we can't claim this one is any good for gaming, it might be a way of expressing appreciation for your better half's love of the brown stuff.
