The MOSS modular robot system is sort of like LEGO Mindstorms, in that you assemble small blocks to make custom robots and other items. But it has some interesting tricks of its own, as product demonstrator John Moyes shows Timothy Lord at CES 2014. The MOSS kits include lots of little metal balls, so they carry a warning that says MOSS kits are suitable for ages 8 and up, while the company's older Cubelets product, which doesn't have the little balls, is supposed to be okay for ages 4 and up. There is no upper age limit specified for either product, so you're probably safe if you want to buy (and can *afford* to buy) any of these interesting toys.
