Aina Aslam built this report. Lego hasn't changed for nearly a hundred years. You build an item out of tiny colorful bricks and then harness your imagination to play with it. The new 2x4 bricks look the same, but have a tiny chip, sensors, LEDs and mini speakers. So you can now move around what you've built and, depending on what you're doing, the bricks light up and make sounds. The technology was demonstrated in a toy car at the CES show.

Here are two D2s hard to impersonate bleeps. And give Darth Vader a dramatic entrance. The Brits will also communicate with each other to decide whether you've delivered enough laser blasts to blow up a spacecraft.

Reactions from parents and older users have been mixed. Some say they would rather pay less and continue making the swoosh and pew-pew sounds themselves. But others are excited for the future, with one fan asking when a Lego Titanic, complete with a smart brick playing Celine Dion's My Heart Will Go On, might hit the market. Aina Aslam, although she didn't commit to the pew-pew noises quite like I did.
