BRIXO's electric bricks
BRIXO's electric bricks are normal sized building blocks that are anything but normal. It's like Lego® on steroids, if steroids also gave you superpowers and taught you new languages.
Basically, they're bricks that safely conduct electricity and connect to your phone to enable you to do all sorts of cool things with your designs. And no, you don't need to buy a whole new set, because they're used interchangeably with your favorite building blocks to add an element of interactive awesomeness.
