... the 35 and 24 Zuiko shifts are very small, compact, and most
of all elegant. Where can I see images of them tilted/shifted...

I'd LOVE to see a picture of one tilted! :-)

They don't tilt -- only shift. :-(

and
how/where do they bend from?

There are two dovetail joints in which the lens shift up and down and side to side.

Also, since each respective lens has an image
circle (correct term?) of a lens of shorter focal length, where does that
excess go?

It bounces around inside the light box, generating considerably more flare than their non-shifting siblings!

The 24, in particular, seems to have more flare than even the SC 24/2.8. But as Doris pointed out, sometimes that can be useful. Unlike the SC 24/2.8, the 24 shift generates lovely multi-colored iris ghosts when shooting into the sun.

Minor correction: the image circle is not that of a shorter focal length, it is merely much bigger than the normal 35mm image circle, thus the total coverage is that of a shorter focal length. Imagine a small portion cropped out of a 35mm frame -- it looks like it's taken with a telephoto, but the focal length of the lens does not actually change. The shift lenses merely crop a section out of what might be suitable for a medium format camera.

On a side note, any reason the 180/2, 250/2 and 350/2.8 are white?

To keep them from heating up in the sun, which causes things inside to expand, which changes focus.
