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 Smart Bricks - tech-filled versions of its small building blocks - which it says will bring sets to life with sound, light and reaction to movement.
