Some would say simple building blocks didn't need improving, but Tegu's idea to add hidden magnets to help hold creations together was genius. And while kids have always been able to use Tegu's blocks to build robots and other high-tech toys with enough imagination, a handful of new sets with added graphics makes it easier to build futuristic creations.
The new Tegu sets range in price from just $20 for a basic kit to $100 for a set with all the blocks and whistles. And they're of course all cross-compatible, so the new pieces will work with existing Tegu blocks, and vice-versa if the new sets get your kids addicted to the line. [Tegu via Notcot]
