Pot shape woes...

[brewmeister83]

So I'm going to make some concrete training pots to move a couple of my trees into next spring, but then a thought hit me "what shape/style do I make them?"

Does anyone know of a book or a web source that's like an encyclopedia of traditional shapes, dimensions, and variations on styles of different pots?

I have this Bookmarked http://www.bonsai4me.com/AdvTech/ATChoosing the Right Pot for your Bonsai.htm it has the general guidelines. My stuff always goes in rectangular and it seems the Wife's stuff is almost always oval. My only variation is for small stuff like accents.
