      Seems like the place to share. Ages ago a group epoxied a webcam and used the random flashes (from cosmic rays?) as their source of randomness.

        I think what they’re referring to is a company - I think it’s CloudFlare - who use a bunch of physical randomness generators to seed their commercial random number generator. One of those seeds is a webcam pointed at a load of lava lamps.
