A client wanted a unique content slider that change a header image and slide text in with a sort of spinning wheel. Not finding anything existing that we could adapt. We wrote our on solution from scratch. Clicking on the top of the round wheel acts as a next button causing the wheel and text to rotate clockwise 90 degrees as new text rotates in from the bottom.  Click on the bottom and the wheel and it will spin 90 degrees anti-clockwise and act as a previous button.
