We get a lot of emails from folks pushing their products at GeekDad, and more often than not, we nod our heads, smile, and say "kthxbye!" But once in a while something comes along that’s interesting. For example, the TwistTogether Lamp. They basically appear to be interlocking light-blocks that you can assemble into any shape you can come up with. I like them as a cool lighting feature for a kid’s room, or elsewhere, too. The price is a little high to go crazy with them ($109 for four blocks), but can’t you imagine taking a whole lot of them and creating scenes from a game of Tetris?
