Will's note to self: CPK is not "ball and stick". CPK is what I'd call
"van der Waals" because each atom is a fat sphere at the atom's VDW
radius.

-----------------------------

Dear Will (and Mark, so you can see what we're up to, comment, etc.),

I've attached a revised set of title graphics that references the 6 ps/s CPK
segment, and have described (inline with the images) what I'd like the
animation segments to contain. The description includes various layered
and blended images, which I hope your software can manage OK.

I prefer tubes mode. It looks cleaner and gives a better sense of the 
structure as a structure, rather than as a collection of atoms in space.
There are two places, though, where I'd like to see a tubes rendering
cross-fade with a CPK rendering. This will let us show how they 
correspond, and do it perfectly clearly without needing any explanation.

I expect us to use this video as THE short introduction to our molecular
dynamics work. With it, other animations will make more sense.

Images and descriptions follow.

With thanks,

Below is a dummy image showing a standard NanoEngineer-1 gradient
background, overlayed with a 20% opacity image (on the same
background), in turn overlayed with a transparent-background text
layer. I'd like to have backgrounds like this, but with a 20% opacity
animation (no time or rotation numbers) in place of the static image.

The most-used animated background would be the motion-blurred CPK view
at 6 ps/s.

The idea is:
1) To spend more time on our best representation of the motion
        (blurred CPK at 6 ps/s),
2) To make the text parts less boring for fast readers,
3) To show motions at the same time as they're being described, and
4) To make the video even more cool.

BUT an animated background at 20% opacity may be too distracting in
slides other than the title and credits....
