Japan-based Trinity has come up with what could very well be one of the coolest iPhone accessories to date – we’re talking about the Fingerist, where it lets you slide your iPhone or iPod touch into its base, starting up an app like Pocket Guitar and start rocking away. A speaker is integrated into the faux wood grain body that is supported by a guitar strap, bringing another dimension to the previously imagination-fueled air guitar. Not only that, you can also plug in the Fingerist into an actual amp to gain your own groupies for some post-show action. The Fingerist will retail for $150 if you are interested.
