(There's no video for iMac System Icons (1.0 + 2.0) yet. Please contribute to MR and add a video now!)
iMac System Icons are 2 sets of icons made to perfectly fit the bondi blue theme of the iMac that came out just a couple months after the release of those icons. I find it interesting to see that this artist actually created and released so many icons before the first iMac was even sold.

iMac System Icons 1.0 and 2.0 / compressed w/ Stuffit
Those are classic Mac OS icons.
