Wish my memory was as good as yours. On a more positive note, I actually found
the files in an old zip file stashed away on my work PC. Funny to re-trace this
image now, I think it took about 2 weeks to draw on my 386-SX 33Mhz PC at
320x240 and even with AA0.05 now is only 1m49s on my current PC. I did not even
need to make any code changes (a couple of version comments had to be removed as
this was for version 2.0).

Glad to have revived it without needing to buy a USB floppy drive.

I am sure this was not my very first image but it was the first proper one I
created once I had learnt how to use POV.
