Images are from Flickr, but individual photographers are credited on the site. Oh, and there are also T-shirts!

Conception

Based on psychoanalysis studies by Martin Sandström, 96pix has a clever algorithm to give the user one outcome out of 12 profiles. Usage is also analysed to give a more accurate result when used the next time. (it's understood that different regions and cultures may react differently to different images, but the algorithm is currently not prejudiced.)
