Periodic table of Fictional Materials

This is very clever and related to a previous post. Alexandra de Groot has created an interactive periodic table of fictional materials grouped by the medium in which the material is reported. I see Administratium made the list of joke elements but the old jokes about the elements Woman (Wo) and Man (Mn) don't seem to be in the table. I am also pretty sure however that Unobtanium (Element # 71 Unb) is mentioned as the ore that drives the mining operation in "Avatar" as well. In any event, this is an epic amount of work and a cool online resource.
