You might not think the picture above is terribly impressive, but...it was taken by a cat.
Seems a German guy living in South Carolina named Jürgen Perthold has modified an inexpensive digital camera so it could be worn by his cat, Mr. Lee (right, with CatCam at ready). Mr. Lee has since become an accomplished and inveterate photographer, dutifully documenting his trips to the woods (he found a snake), his water dish, well-framed views of his house from a distance, and so forth. Presumably, the picture above, taken from underneath a car, is a portrait of one of Mr. Lee's associates. The modification of the camera wasn't trivial, either—the CatCam website takes you through it step-by-step, just in case you should be the owner of a cat and in dire need of a project. (The website has gotten so many hits that its former hosting service banned it. The link is to Mr. Lee's new online representation.)
Meanwhile, over on the Rangefinder Forum, Dr. Leo B.—presumably dissatisfied by the M8, or else acting under the "Mt. Everest Principle"—perpetrated the following on an otherwise innocent Leica M3. Voilá—digital rangefinder. Although its creator admits it's ugly, it actually works, making Dr. B. at least three times as clever as me.
Featured Comment by David Goldfarb: The idea of putting a small camera with an intervalometer on an animal is not entirely new or ridiculous.
Here are a couple of photographs of Julius Neubronner's pigeon camera, patented in 1903.
Pigeon cameras were used for aerial reconnaissance during WWI. You can find a hi-res image of a WWI pigeon camera on this page.
Since the flight path of a pigeon is somewhat more predictable than that of a cat, the timer could be set to improve the probability of obtaining useful images.
Mike adds: And I feel a potential conflict brewing. God forbid a cat with a CatCam should eat a pigeon with a spy camera...the visuals don't bear contemplating.
Seriously—thanks for this, David.
