If you want to showcase some fancy buttons perhaps of social media sites or other content then this pure css direction aware flip buttons might come in handy. It was designed by Gabrielle Wee. When you hover over the square the button does a flip in that direction, so depending on where you hover from the button will flip in that direction.
