Hello /wg/. I need the help of an oldfag.

I seem to recall that there are several papes somewhere in existence that are much like pic related. A few years ago I had a folder full of them and I don't know what happened to it. Kinda just realized that it's gone and that I really liked those pics. Anyone have them or something similar? The ones I'm specifically remembering are like shots of the clouds lit by sunset by they were drawn with pixels.

I've searched just about every term I could come up with. Any help would be appreciated.
