Lego unveiled its most ambitious product in nearly 50 years at CES 2026. It's called the Smart Brick — a 2x4 Lego brick with an entire computer inside. The brick contains light and sound capabilities, motion sensors, a microphone, and Bluetooth mesh networking that lets multiple bricks communicate with each other.

Lego has unveiled new high-tech “smart bricks” it says will bring its classic toys to life with lights, sound and interactive movement.
