On photo sharing site Flickr there’s a new group pool called Macro Machine Stuff (and things), where the main thrust of the user-generated and member found photographs are pure, delicious machinery eye candy. Macro and micro, or just focused detailed images of pumps, assemblies, wiring, gearing, engines, homemade boxes of all kinds, and all manner of unusual mechanical creations -- close up. It's pretty much machine art pr0n, and the photos are stunning.
It's a small but quickly growing community, and is a fabulous addition to the RSS reader for an occasional dose of machine art beauty of the most mysterious kind; often, we have no idea what we're looking at, but love what we see. The occasional video is also a nice treat.
