When I was playing with the laser, I aimed my phone camera at it. The laser was operating in pulsed mode, with low average power but high peak power. I didn't notice any damage back then.

A month later I went skiing. Was taking pictures with my phone. And found some UFOs on photos!! What tha?! Look at these orange strokes in the sky (not at Valluga bahn =)

On most photos, one has to look carefully to notice, but on blue sky the damage done to sensor is very visible. Oops!

This leads to a very surprising and totally unexpected conclusion. DON'T LOOK INTO THE LASER WITH THE REMAINING EYE!! No, really, don't.
