One of the most recent videos/talks is given by street artist JR. Many of you may know his work, but not his name as he rarely signs works, and is more interested in using art as a method of change on a larger scale rather than a path to his own personal bank account. Checks it YO!
JR also makes a request/challenge at the end of his video. Asking anyone and everyone to submit a portrait, and help create the biggest art gallery ever (ie...the world)
More info below;
Seriously...I am going to take my portrait...you should too!
Also check out the rest of the Ted Talks and become super smart!
