Most of the heavy lifting has already been done for you, as aka_arduinna has created a master list for Invisible Man. Very, very useful since I-Man stuff is spread out and can be easy to miss. I'd passed on my I-Man vid list during the gathering phase, though aka_arduinna already had most of them on her own list.

aka_arduinna: I've scoured the web and come up with what I hope is a fairly complete list of I-Man stories, writers, vids, archives, mailing lists, LJ communities, transcripts, and episode guides.

And though there are relatively few I-Man vids, there are some choice vids. To list just a few: Seah & Margie's own "Kryptonite", Clucking Belles' "Voodoo", Fabella's "Thief", Lithium Doll's "Karaoke Soul", Sisabet's "Weeping Willow".
