I'm far from a UI wizard, but I think I understand a lot of the perception 
issues and/or I'd like to learn more.

I've always thought of "slide into view" as annoying.  I have to wait around 
for the thing I want to look at to finish dancing.

Is there a good book or paper discussing this area?  Does one of Tufte's 
books cover this stuff?
