Soundcamera - visualizes sound - useful for our hobby?

I saw a kickstarter for a audio visualization device and wondered if it had application for audio designers or end users?  There's a video that explains it all.

Aparrently devices like this exist but are 100,000 or more and require complex set up. This device is about 5000 euro.
