These are 3D Profile Flip Cards. Click the i to flip the card. The concept started out as a hover event, but that proved challenging on a mobile device, so I opted to use a bit of js to change out classes on click/touch.
There are a variety of flip options, Y, X and Diagonal
This was inspired by Rich Bradshaw: http://css3.bradshawenterprises.com/flip/
Images were from random Google search... I apologize in advance. Maybe I'll switch it out to placekitten.
