Designer Richard Clarkson experiments with products, lights, and furniture and one of his most elegant creations is Cloud, an interactive light cloud that simulates a thunderstorm.
From Richard Clarkson’s website:
The Cloud is an Arduino-controlled, motion-triggered lightning & thunder performance, as well as a music-activated visualizing speaker. As an interactive lamp and speaker system designed to mimic a thundercloud in appearance, The Cloud employs embedded motion sensors to create unique lightning and thunder shows while providing entertainment value and inspiring awe. This is a kind of magic, not based on illusions and trickery, but on sensors and code. Featuring a powerful speaker system, The Cloud allows its beholder to stream music via any Bluetooth compatible device and can adapt to any desired lighting, color and brightness.
