With the Speaker Cube, kids (or anyone else who's interested in tinkering) can learn step by step how to make a device that reproduces music or other types of noise. Not only that, but they're able to customize the speaker to their liking, with different covers and a variety of colored lights. Of course, since it is a Bluetooth speaker, the Cube pairs easily with smartphones or tablets. And hey, it's okay if you're not a kid but still want one.
