sourcing
the nature of this sort of internet emphemera is that sourcing it is hard. many were collected from second-hand sources. it's an ongoing project of mine to try to find what sources i can in the interest of internet culture preservation, but it's very much a work in progress. as sources are found, they will be linked on the image itself (or, in the case of known but unarchived sources, put in the hover text.) if you know a source for a pixel, you can send an email to salt.forfun [at] gmail [dot] com.
otherwise, here are a collection of primary and secondary sources you can find more content like this!
