Some of the earliest things I made on a computer were icons. Icons were a bigger deal back in the days of Windows 3.1's Program Manager. I was so compulsive that I had program groups set up for different categories of audio clips I downloaded (probably from AOL 2.5). Then I started making custom icons to assign to the sounds in these program groups.
Part of the fun of it was that with only a 32x32 pixel canvas and 8-bit color to work with, you knew they weren't going to look great. You just do your best within the constraints of the medium and you have a convenient excuse for anything that looks like crap. Of course those were the old days, before high resolution 32-bit color icons.
