This is a cool effect, I thought it was the panorama trick, which is also great fun. I read recently that Samsung phones now lay a shot of the moon over your inevitably crap glowing shaky shot you tried yourself, fooling people in to thinking lunar photography is easy

It’s her arms in the mirror if anyone is wondering.

Your eyes / brain do the same thing, but 50x funkier. Your vision only sees colour in the centre (+/- 10° arc), but the centre is blind in low light. In a dark room you can’t see things by looking AT them, you have to look 15° OFF them to see them! Try it.

You have an optical blind spot where your nose is, your brain just imagines what is there. Same for the peripheral of 60° - 75° which is actually the largest area of your field.

Most of your field of vision is literally imaginary.

“I saw it with my own eyeballs” is not the claim people think. And this is before we talk about how lossy human memory is and how memory recall actually overwrites!

We’re really messed up, quite a lot of bugs still. But evolution was a work in progress and did a pretty awesome job to make all this cool stuff from supernova debris.
