I've also got some interesting sites ( some are in combination with maps )
http://tcat2003.chez-alice.fr/
http://www.geocities.com/thesirclan/frames/pod.htm
http://dwl.17buddies.net/
Maybe I will search some more and post them here.
I'm currently saving all interesting links for any of my interests in a text document so I won't be cursing my guts out for searching that marvelous website I saw yesterday ( not that this specificly happened, it's more an example )
