The cloud is an Interactive Thunderstorm in Your House
This cloud is an interactive thunderstorm light and a speaker.
From clarkson's website:
"The Cloud is an interactive lamp and speaker system, designed to mimic a thundercloud in both appearance and entertainment. Using motion sensors the cloud detects a user’s presence and creates a unique lightning and thunder show dictated by their movement. The system features a powerful speaker system from which the user can stream music via any Bluetooth compatible device. Using color-changing lights the cloud is able to adapt to the desired lighting color and brightness. The cloud also has alternative modes such as a nightlight and music reactive mode."
