Hey there Ian,

I know the project is in low maintenance mode, but if you ever get to polish
it up again at some point in the future, could you add some more explanations
about some of the CSS effects?

This does not necessarily need to be in the main README file; it is ok to
add it elsewhere, be it on the wiki, or examples/ or doc/ - and link to that
from the main README.

Specifically - which explains the use case of this issue - I am wondering
about the "rotate" effect. Right now it tilts a bit to the right. I wonder
if it is possible to change it to the left. I assume so (I haven't looked at
the CSS yet), but I sometimes make mistakes, so having a short
one-liner example to demonstrate how to tilt to the left, would be
useful, IMO. That's just one example I can think of right now, perhaps
some more effects (the non-trivial ones) need more examples. Most
effects such as grow and shrink are super easy to understand.
