The shadow imaging hack to avoid lenses reminds me of the single-pixel camera that produces the image via random sampling http://www.ece.rice.edu/~duarte/images/csCamera-SPMag-web.pd... I love this kind of hack for some reason.

There's also the optofluidic "microscope-on-a-chip":

The lensless optics are similar to the cellphone microscope, except that there is virtually no distance between the sample and the sensor. Also, the sensor is a one-dimensional array of CCDs; the sample is "scanned" by propelling it over the array in a stream of fluid.

Offtopic: The first comment on that site is priceless.

Does anybody have a link to a good explanation of how it works?
