1) My concept is of me doing the Sudoku over and over again. I arrived at this idea because I used to have this habit of doing the Sudoku and Ken Ken in the AM NY newspaper whenever I am just feeling off or I am mad. It helps to get my mind off of things and help me feel better. The image of the Sudoku in the GIF reflects that, and the action of the completion of the Sudoku.

3) Originally, it was just going to be a simple Sudoku puzzle being solved, but now it's a puzzled being solved to messing up on a number and erasing everything to start over. To be honest, the animated GIF has not changed a lot but I feel really proud with it and I put a lot of time and effort into it.
