Here's a project in the same vein that turns cellphones into a distributed telescope: http://www.distobs.org

Wow, that sounds very exotic, but it turns out it is practical. Who knew? This project is much more distributed and interesting than the SETI. I will keep an eye on this project.

Fantastic innovation, similar to the "why didn't I think of that?" article that was on HN front page yesterday about the university student who made that new UK plug that takes it from one of the largest to a slim design.

Sort of a misleading title presuming that all cellphones have a built-in camera.
