After watching Mark Ramm's TurboGears One Page Reference,

Here are parts of them (that I've tracked):
and related Cherrypy API
Notice that a part of notes in these MindMaps are based on Mark Ramm's One Page Reference.
And it's even better if someone intrest to make a more fancy quickreference based on those early works.
