Jigsaw puzzles require players to sort and arrange tiles to reconstruct some image. What if instead the tiles were pieces of some video instead?
The idea for this concept is not my own. Many years ago I came across an online game that implemented this. An animation of three mines bounced around a square was shattered into a number of square tiles and the player had to arrange the tiles to fix the animation. Unfortunately, I can no longer find the source of this game to credit it. (If you have any idea, please let me know.)
The graph linked above is an implementation of this idea where the completed puzzle is 4 by 4 tiles, and the animation is of a conic section with changing parameters. Clicking on a green tile reveals a black dot that can be dragged to move the tile. Clicking away deselects and makes the black dot disappear. The orange button in the bottom left resets and shuffles the tiles.
This seems like a setting where a timer would be interesting/appropriate, but I believe I created this before I knew how to implement timers in Desmos.
