It actually doesn’t need to be so elaborate. Even a video camera with the lens cap on generates more than enough entropy. Your phone can mix together predictable but unique variations - time of day, free memory, CPU serial number, battery level - with less predictable physical sensory - light level, gyroscope, barometer, last touch points, nearby MAC addresses - to create far more on-board randomness than anyone realistically needs.
That said, the whole Cloudflare lava lamp thing is very cool and also gets people talking.

interesting. Never heard this before. How is the entropy created? Wont all the values for the pixels be near zero (extemely simplified)?
definitely cool, i want a wall like that. it would be a lot better than the one i kept tipping over and burning shit with in my tiny room at the time
