Developed by the Lego Group’s Creative Play Lab, the Lego Smart Play system will make sounds and activate lights based on player movements and builds. Lego says the new platform "features more than twenty patented world-firsts," including a new custom-made chip that's smaller than a standard Lego connector stud.

Lego has unveiled new digital “smart bricks” that light up, emit sounds and respond to movement in its “most revolutionary innovation” in nearly 50 years.
