i know autopraxis, burning down the house, kittyquest, vast error, and spicyyeti's excellent website comics. played meenah's route on befriendus. if this collaboration featured the mysterious comebacks of the tapestry and you're someone it'd be a dream come true, but of course many of the best things are lost to time. then there's john ruins a wedding which i'm reasonably sure is unaffiliated, and i also like what was presented in karkat goes to a convention.
