http://www.ffffound.com is a site were users upload interesting pictures, sometimes photos but mostly illustrations, that appeal to an aesthetic. These aren’t jokey pics, so don’t expect to see kittens falling off tvs. The best bit is that when you click an image you go to a page with similar images. Hours can disappear from your life by just following the images. Its awesome.
I’ve made a screensaver by batch downloading a whole bunch of ffffound images and then point my slideshow screensaver to that folder. I’ve got about 5,000 images and the best screensaver I’ve ever had. Coolest thing is I got 3 screens at work and each of them displays different images. Bliss. 
Got an invite for me?
They’ve been invite-only since I can remember. I’ve resorted to using delicious.com and tagging all my found images with “picture”.
You don’t need an invite to visit the site and rip the images with a batch download tool. I’m not registered.
Ah, I figured you had an account. Damn
