The wet bird (2000)
I remember when this one came out and letting my computer spend insane amounts of time rendering images. There is something about POV-Ray, its limitations and interface (or lack of) seems to make it excel at this sort of half real impressionist style while never entering the uncanny valley. Or maybe POV-Ray just attracts people who work towards that style. I miss the POV-Ray community and spending weeks coding an image and 14 hours rendering an image just to find out you made one tiny stupid error and have to do it all over. Last I used it I had a 1.8ghz single core processor, I wonder what it is like on a modern computer.
