The Danish global toy company LEGO unveiled at CES 2026 a ‘Smart Brick (LEGO parts)’ that reacts with light and sound based on children’s movements and manipulation methods and can transform into various roles.

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.

The small plastic bricks will be packed sensors, speakers, lights and an accelerometer to measure how it's being played with.
