Photo frames to be heard as well as seen
Hidden speakers could come in handy at work when the boss isn't around.
As long as some people simply can't stand leaving their USB ports unoccupied for any length of time, here's at least one way that they can be used without making a fool of oneself while saving some desk space at the same time. The "Photo Frame Speakers" will blast away in stereo from behind the frames on either side of the computer, though the pictures aren't digital--not exactly seemless technological convergence, as Everything USB notes, but it'll do in a pinch. Especially if you use them at the office while your Metal Gear Solid 4 headset is recharging.
