If you’re anything like me, your office probably has a lot of geeky and/or nostalgic items sitting around. From Star Wars figures to classic gaming pieces, it’s anything from dull and boring. What is really fun is when you can find something that not only fits with the theme of your room, but also provides function. Take, for instance, this Rubik’s Cube Speaker.

This speaker will connect to just about any music source, via a stereo jack. Power comes from your computer’s USB port, and a 5W speaker plays your favorite tunes. The only disappointing part is that this cube is completely stationary, so your puzzle-solving skills will not get tested. Then again, maybe that’s a good thing (if you aren’t any good at solving Rubik’s Cubes). Just $30 will get you one of these awesome retro speakers.
