How many ways to fold/ cut the same basic square card..

Have you ever just taken a basic square card and tried to find as many ways as possible of using the same thing to create different results? Well, I've been making myself some mini templates to use with different coordinating papers etc and am finding it hard to stop! Some are very basic and others have quite a little bit of folding and cutting but they all come from the same square. The one at the back right is made up of two cards joined together.
