Is this the program?

The video above claims it's by Tim Clarke.  YouTube commenter says

@Myndale (8 years ago).  This was mind-blowing when it was first
released. As soon as it came out I released a TSR with hot-keys to
change the palette so I could see how well it looked on other planets
(notably Earth).  I also spent weeks pouring over the asm in order to
understand exactly how he did it.  That work formed the early groundwork
for much of the work I did over the next 16 years working in the game
industry.  Years later I would write my own version of this demo, figure
out how to add rotation and then port it to several architectures along
the way including DS and even Javascript (see
http://www.ppl-pilot.com/demo.aspx). But Tim did it first! :)
