PhotoSketch is an “Internet Image Montage” project from five students at Tsinghua University and the National University of Singapore. The basic premise, which they present in the form of a research paper [pdf], works like this:
Draw the outlines of the figures you want in your picture – anything from seagulls to a wedding kiss;
Add labels for each of the items, as well as for the background.
PhotoSketch will then find real-life images to match your doodles and put them together in a Photoshopped image that will make your jaw drop.
And before you say "it must be fake", download and read the research paper (in pdf), already evaluated by the scientific community.
In Bb 2.0 is a collaborative music and spoken word project conceived by Darren Solomon from Science for Girls, and developed with contributions from users. 20 different YouTube videos embed in the same page, each with one instrument playing a tune, but where harmony is very well achieved. The videos can be played simultaneously - the soundtracks will work together, and the mix can be adjusted with the individual volume sliders. And you can combine any choice of instruments and play a different music each time, worth a try.
