The project I’m Google by Dina Kelberman is amazing. It’s an almost infinite collection of photos, hand picked by the artist.
The collection is so large that it’s hard to reach the end by using the tumblr site. Also, you do need to scroll. As a couch potato myself, I did the only thing that seemed to make sense: a couch mode version.
The main difference is that you don’t need to scroll and it starts at a random image. Perfect for a screensaver !
I wrote a script to fetch all images from the original tumblr and generate a small app with it. The code is on github.
PS: If you too spend way too much time in couch mode, maybe you’ll like Passive YouTube as well.
