I thought people always use animation and CSS3 stuffs in their pens, so what could I come up with, that is cool but without any modern bling. So, I created a simple pen (http://cdpn.io/GBleD) illustrating classic golden ratio using nested div. Would love to see some other interesting pens from you all.
