Harvard machine learning experiment

It's a bit abusive of the Harvard brand to throw the name in a post just so you can get some training data for model. At least include a writeup of what you're doing so people who click through get something out of it too.

Hi guys, I'm running an experiment for one of my courses and need to collect some data. I would really appreciate your help.<p>Thanks!

Wow, these pictures are really cool! What is this experiment all about?
