Design, performance art and clever security infrastructure come together at CloudFlare San Francisco. A wall of lava lamps has been integrated into the office design, with a constant feed of photographs of the fluid dynamics delivering random number generation for use in back office processes.

Cloudflare turns the “Wall of Entropy” into encryption using a camera that photographs the wall every millisecond of every day of the year. Any one of the company’s systems can turn the display of pixels–which changes based on a multitude of factors, like the movement of the lava, the inclusion of anyone who’s walking by, and the shifting daylight–into random numbers…

According to John Graham-Cumming, Cloudflare’s CTO, the lava lamp wall generates 16,384 bits of entropy each time it is used.

Interior design meets infrastructure design. I love it.
