LEDs, Sensors, & Sound = an Interactive Thundercloud

LEDs, check. Speakers, check. Motion Sensors, check.  Put those all together along with some fiberfill casing to create an interactive thunderstorm!  Richard Clarkson Design Studio created the "Thundercloud" to create a unique lightning experience.  The cloud comes in at $3,360, and you can purchase it here.  You can also get a simplified version for under $1K here.  What types of applications would you use this in?
