Press the space bar to turn off the white and black circles In the beginning, you might think the two circles are flashing at different times, but think again! When you press the space bar it will turn off the white and black circles in the back that aren't flashing, and you will see that the circles are actually flashing in unison. Try it for yourself, and if you don't believe me, you can see inside this project to take a look that I don't change the blinking state of the circles.
