This is an electronic take on the classic children's toy SpiroGraph. Five colored lines endlessly weave band of color with a virtually unlimited number of resulting patterns. Using slider controls, you control exactly how fast the lines lines revolve and rotate, their size, their color and their width.
The 'standard' Spiral plot uses creates lines using two connected 'arms' with the endpoint of the second arm tracing the paths of the color band. The 'deluxe' setting uses three such arms, with even more fantastic resulting patterns.
You can control the exact resulting ever-changing image but the app also has a chaos mode that automatically creates random patterns. Absolutely mesmerizing!
