To give credit where it's due, the 32 colour King Tut image that Deluxe Paint's mascot was drawn by Avril Harrison. More of her graphics: https://www.amiga.lychesis.net/artists/AvrilHarrison.html

(I see the article now credits her on the image subscript?)

Also, the article mentions the colour-cycling animations of Mark Ferrari, but you might also like a big collection of specifically Amiga colour-cycling animations: https://www.amiga.lychesis.net/specials/ColorCycling.html
