Self-Adjusting Sunscreen   (+4, -3)  [vote for, against]
Auto-Dimming particles in lotion

We have glasses and welder's masks that auto-dim to shade the eyes from harmful light. Couldn't one apply the same principal to sunscreen so that it allowed a constant amount of light to the skin? Could you also apply this to paint? This would allow for different pictures for different light levels.

Sometimes there's just not much to say. It's a sunscreen that self-adjusts, based on a technology the poster doesn't understand.

Is this magic? I thinkthis is magic. Maybe not the science or the process, but the application of the process.
