This page will turn a list of tumblrs into a rapid-fire slideshow of stills that continually changes. While you could hypothetically use it to look at pictures of kittens really fast, it's more useful in, um, other ways.
Pick a set of tumblogs or enter your own (separated by spaces).
You can do literally anything. I know this list probably doesn't have one (or any) of your favorites in it, but I'm not you! Help me make a good list.
The Gooninator scrapes all image URLs from each tumblog's image posts and continually downloads new random ones to a queue in the browser. While this is happening, another loop goes through the queue, advancing to the next image based on the timing function you select. If the images are being displayed faster than they are downloaded, then a random one will be shown from the past 120 images.
