David Ope is a “Animated GIF Artist”, something I’ll admit I didn’t even know existed. He creates various mesmerizing, if not a little eye-straining, animated GIFs. Many are his own designs — mostly black and white striped compositions — but others are found media pieces featuring everything from himself as a baby to solar flares. I’ve included stills of some of his work above, click each to view the animated version — didn’t want to get all Geocities on you.
Be sure to check out his blog, where you’ll find all sorts of interesting work beyond his own portfolio, like this superb example below (possibly the best animated GIF ever made). Amazing to see people pushing a near-dead medium in such interesting directions.
