In the Windows 3.1 era I compiled different icons I could find into packs that I sold as shareware, taking $10 orders via checks in the mail and sending out 3.5" floppies in return. This is much better.
Haha what I like about those icons is they're actually pretty effective at grabbing attention. That retro/throwback thing. Thanks for the link. Now I gotta find out if they're open source ;)
Hahaha oh boy: I may have been one of your customers. I had literally hundreds of folders of icons that I also wanted to keep offline incase the site went down. It was such a pain managing them.
