Going through old photos from my Twitter archive, this is an attempt at directed evolution in software using PHP (precisely the wrong language to use, but I was learning it at the time and it was a useful exercise).
The program throws a randomly sized, coloured (rgba), positioned and orientated ellipse at the "canvas", compares it to the target image, and keeps it if it's closer. This is about 150k iterations, and took something like 12 hours. Not brilliant, but starting to get somewhere on a P2

Ah, that time there were no pumpkins in the shop at Halloween (or turnips, which is more traditionally Scottish, and smell foul with a candle in them). This, however, mmmm, tasty. Circa 2011.

This is how old pylons are removed from remote areas like the Cairngorms.

A cold Highland night, temperature dropped in the right way to cause a dew film, and then rapid nucleation/freezing.

@_thegeoff When I was a kid, we were stationed at Edwards AFB (near Mojave Desert) when my dad was in test pilot school. They had been flushing fire hydrants one day, and I recall laying in bed, seeing the moon out my window, and the it was like the Dementors ice crystals (from a certain author I won't mention), growing over the glass. They looked a bit like this and formed in a few minutes. sudden drop in temp and general low humidity of the area had interesting effects.

@_thegeoff I think I was 7. I'm in my 50s now, it's one of the core memories of my childhood watching those grow.
