It’s a 2 x 4 Lego brick with a speaker/lightsand custom ASIC built-in, with light and sound sensors, reacting to IOT beacons that allow different sounds or light sequences. And it’s rechargeable like an electric toothbrush. It also has accelerometers that change the sounds as you twist and turn them around. The sounds themselves are generated, with the speaker driven by an onboard synthesiser.
