The most interesting challenge I encountered is how to make the five

circles move together from different positions. The first two circles are

easy, but when I code five circles together, The rest of the three circles got out of control. I forget "-1" represents the opposite direction at the beginning.

Two circles got out of the frame of canvas and another was always shaking on the y-axis. I tried to adjust my codes a few times and found the circle of the initial position is wrong.
