This is pretty "old" news but I still find it fascinating enough to share.

Sooo.... "Researchers at the University of California, Berkeley have developed an algorithm that can be applied to functional magnetic resonance imaging (fMRI) to reconstruct YouTube videos from viewers' brain activity." (sited from the first article in the below link).

They can't actually read your mind but those reconstructed images are surprisingly similar to the videos which were shown to their subjects. Let me know what you think.

Here are some article links:
