Today you used cutting, folding and gluing to create your pop ups. All pop up books or cards, whether simple or complex, are made using the same simple mechanisms. If you click here, you will find the instructions for these mechanisms and some more complicated ones.
If you watch the video on the left you will see how the paper engineer Matthew Reinhart takes the same mechanisms that you used today, and develops them into speculator pop ups.
Could you develop and improve your basic design into something amazing?
