this is maybe one of the BEST sites i ve discovered in the last days..
these guys pick scenes, mostly from old movies, choose 3 frames and make amazing .gif images.
and the best thing, the site has been running since 2009 and IS UPDATED EVERY FREAKING DAY! so they have much much material.
+ its on tumblr so viewing the images in archive is very convenient.
check it out! [ http://threeframes.net/ ]
