By request of BWOG... Position the three dots where you want them, then press the Draw button. Red Dot - Remains stationary Green Dot - Is the "Puller" dot; it attracts the Blue Dot. Blue Dot - Moves towards the Green Dot until it reaches it. A line is drawn between the red and the blue dots to create a string art type effect. For an interesting effect, you can drag the green dot around as the blue dot is moving towards it to make more fun patterns!
