I haven’t really gotten into the whole tumblr/tumblog thing yet, seems like an interesting way to blog easily/share with friends. I see it an am amped up version of twitter. One enterprising individual has managed to make his/her tumblog into some weird trip art blog. By taking 3 sequential frames from movies and making animated gifs out of them (which I can’t seem to recreate here, help?), Three Frames really adds dynamic to an otherwise boring image.
For another set of images check out Keggers of Yore, which documents keggers from what seems anytime before the mid-80s.
