Guitar Video Game Cufflinks" from Cufflinks.com? The French cuff peripheral is a mere $50 -- no word if star power will activate every time you put a phone to your ear.
While we're talking cuff links, the site also has sterling silver Wiimote (with Nunchuk backing) and DualShock sleeve flair for $150 a pair. No Xbox cuff links?! Fanboys, attack! Cufflinks.com is too bias!
