Smaller Original

This puzzle consists of four pages, colored red, yellow, green, and blue; and four frames (to the left of this one) all of different shapes. Any of the four pages may occupy any of the four frames. When a page is in a frame, it will have a button visible in its lower right corner: a different button for each of the four frames. If this button is clicked, it will cause a page (indicated by the color of the button) to appear in a frame (indicated by the shape of the button).

The objective is to cause the red page to appear in all four frames, as shown in the picture at the top left corner. Unfortunately this will produce no special effects, apart from the knowledge that you have solved a surprisingly difficult puzzle.

If you have a high-ish resolution video mode, you may prefer a larger version of this puzzle (which also has an unimportant bug in it, not effecting the solution).
