Tumblr is a bottomless source of wonderful things. Most recently I stumbled upon a blog called Angular Geometry (or Angular, in short), where a graphic designer, whom to my deepest regret I do not know, posts myriads of myriads of beautifully animated GIFs.
The images are looped and hypnotizing. Transitions between frames are seamless and it is easy to zone out whilst watching abstract and natural forms create mesmerizing shapes and dance on the screen. Particularly noticeable is the attention to detail and craftsmanship that the designer has put into lighting and physics. They're perfect and seeing the figures bounce, vibrate, ripple, and rotate is a true pleasure.
We've selected and put together a list of 20 great GIFs we'd found on Angular Geometry, but be sure to check out the blog as well. It's full of secrets and treasure.
