A nice tutorial about "Creating a Flippin’ 3D Countdown with CSS & JavaScript".
Flipping Gallery let you create a simple but beautiful 3D flipping gallery using minimal HTML markups and one JS call.
Here you ll learn how to create a little component with a realistic touch. The idea is based on the sweet paper effect found in the video of the Google Developer Stories.
We’ll create a circle with a handle which will open once the little handle is clicked, creating a realistic 3D flipping effect with the help of CSS 3D transforms and shadows/gradients.
