dear qis, I'm glad you appreciate the joke! yes I do intend on making more desktop pets in the future with different ideas I have! I agree that their design has to be sensitive so that they don't end up being too obfuscating or too distracting, and I think that makes it interesting. The idea of having a fiddle on the screen is really interesting, I like it!
Simple desktop sprites sure can be good fun on their own! Sadly many of the desktop pets from their golden era are not compatible with modern OS, or are simply lost to the internets. But still we can hope for the rebirth of desktop pets as a popular thing. :)
