YOU CAN MAKE IT TOO!
Steps:
1. open MS Paint
2. choose option of making a thick-lined circle of a vibrant color choice(red, pink)

3. make a square shape out of a select grid and pull it out. You should end up with the circle being split. One now has pieces of the sides and top and bottom of the circle, other now has corners of the circle.

4. Put large grey solid dot on inside of the circle with diagonals of other broken circle

5. grab other piece that doesn't have grey dot, and slowly move it vertically over the other piece(with grey dot).
If you did it properly, the sides of the circle you are moving should appear to tilt to the side!!!
