This might be better in talk about, more response and room for inevitable technical discussions.
A few shots have been shown, a search may find them. I can't show any shots as I don't have a T&S, but I can help on the theory.
It is worth noting that when focused at infinity the lens tilt available is sufficient to tilt the sharp focus plane to 90 degrees, however this reduces dramatically as you focus closer. Typically only about 16 degrees of tilt can be obtained at life size (using equations here http://www.zen20934.zen.co.uk ...raphy/tiltshift.htm#Close Up).
This can be illustrated with this plot, showing the tilt of the planes of sharp and acceptable focus (ie the planes of depth of field, this is not affected much by focal length.
Of course you can use focus stacking to improve DOF for some subjects rather than T&S, most obviously mushrooms, flowers etc that would be good applications for T&S.
I would be interested in hearing from anyone that manages to use lens tilt handheld with insects.
