Lensless Microscope — DIY How-to from Make: Projects

''Behind the lens of a webcam is an imager chip with thousands of tiny light sensors, each about 1/10 the diameter of a human hair. If you replace the lens with an LED light source, and place tiny objects on the imager chip, shadows will project onto the sensor, creating a lensless microscopic image.'' [source]
