Jin(Shizen no TekiP)’s homepage went up at IA PROJECT! (Even Shidu’s going to have a page, it seems like!) There’s his profile, a discography of all his albums and compilation albums that he’s taken part of, and the last tab is a song list. You can check each song to see the screencaps/images for it, as well as the albums it’s a track for, and a link to the video on NND if it’s available.

Some of the songs from Mekakucity Days don’t have PVs, so they use the generic city backdrop image (Dead and Seek has a slight variation), but for Gunjou Rain, there’s a new illustration! Or it might not be new if you have Children Record, since it might be from the booklet, but I’d think most of us haven’t seen it before.
