Think your Exilim is pretty thin? If the engineers at UC San Diego have their way, you ain't seen nothing yet. They're working on a new telephoto lens that unlike today's lenses, can be folded allowing for a smaller, slimmer camera, which can then be used on spy planes, in cell phones, or to make your Exilim rail thin. But don't trade your Exilim just yet. The "origami lens" is still going through some tweaks before making it's debut.
