Eyepainter, if you enjoy seeing and learning about prints. You should definitely track down 4K77, 4K83, and (soon) 4K80. You don’t have to have 4K equipment. There are 1080p versions of all of them.
I was able to find 4K77 on archive.org but can’t find the 1080p version of 4K83. All the torrent sites (I prefer not to use usenet) have the 2160 version)
