You might have thought you’d seen every possible size and shape of brick and accessory, but the brand is about to ruin your complacent attitude to your Lego basket. Lego is bringing interactive bricks and minifigures to new kits.

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.

The new brick looks and clicks into place like a regular one but its advanced electronics sense other smart bricks and minifigures and respond with real-time audio or light effects.
