I got into a conversation today about the greatest examples of creativity throughout history, and all the things they share in common. It was really fun to bounce from Sphinxes and pyramids to Pollock to Mozart to Shakespeare to Hendrix to Oscar Wilde, DaVinci, Michael Jackson, Cezanne, Martha Graham and Alvin Ailey, Antoni Gaudi and Johnny Cash. FOCUS: No limit, no specific medium, no specific time period - give an example of one of the greatest things humans have ever left behind. Link it, explain it, justify it. This isn't a thread to tell us you think Death Cab for Cutie is an awesome band - let's keep it to things that are historically great.
