The other is lens shift and tilt capability. Shift and tilt allow the focal point to be moved across the film, or angled across it for perspective correction and unique effects. With the development of fluid lens systems by Philips and others, shouldn't it be possible to dynamicaly alter the shape of the fluid lens to provide a the same effects as shift and tilt?

This would allow for a compact lens and camera combination that incorporates the advantages of shift and tilt without the bulk and mechanical complexity. Fluid lenes are already vari-focal, it shouldn't be too hard to alter the system to provide these features. Non-symetrical electroweting combined with conductive fluids (liquid crystals?) could produce any number of unique lense shapes on the fly.
