A very cool demo about what you can do if you take the time and patience to do it. This guy made the Capitol building out of no less than a 22,000 cards, and made a time-lapse video so we can watch and enjoy!

Using functional magnetic resonance imaging, researchers have been able to associate a brain activation pattern to the memory of an image. According to a study in Nature. Reading the thoughts of other people is not yet possible, but scientists are working on it. One tool developed by Jack L. Gallant and collaborators at the University of Berkeley (California) is able to recognize an image that a person has just seen through his brain activity. Two of the authors of the study published in Nature - Kendrick Kay and Thomas Naselaris - were submitted in person by observing the experiment at random photographs from a group of 120 during brain scans using functional magnetic resonance (fMri). The results of fMri, combined with a mathematical model, have served to associate the images neuronal activity that a person has just had before our eyes.
