I noticed some really neat images flowing past Jason's computer over the last week. Whenever Jason was away from his desk, our section of the Echo Nest office would be treated to a very interesting slideshow - mostly of musicians (with an occasional NSFW image (but hey, everything is SFW here at The Echo Nest)). Since Jason is a photographer I first assumed that these were pictures that he took of friends or shows he attended - but Jason is a classical musician and the images flowing by were definitely not of classical musicians - so I was puzzled enough to ask Jason about it. Turns out, Jason did something really cool. He wrote a Python program that gets the top hotttt artists from the Echo Nest, and then collects images for all of those artists and their similars - yielding a huge collection of artist images. He then filters them to include only high res images (thumbnails don't look great when blown up to screen saver size). He then points is Mac OS Slideshow screensaver at the image folder and voilá - a nifty music-oriented screensaver.
