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!
What's New in Version 1.2
The display has been sped up, screen refresh is nearly twice as fast as it was.
The link at the end of the 'about' section has been corrected.
Portrait and upside-down portrait orientations are both supported.
Hypnotic and Awesome!
Holy moly this app is cool. I just spent some time letting my son touch my ipad for the first time - playing this game! He was positively entranced by it.
Don't bother reading the opening page of text - you don't need it. Just click through to the UI and let the spirograph do it's thing.
The two buttons you should first experiment with are Random, which will mix up the settings so you can see what's available, and Chaos, which varies the settings while the animation plays. You can also select and change the colors of the lines displayed.
Biggest problem I have is that you can never see a completed, symmetrical design, since the lines are always being erased at one end as they are drawn at the other. If there were an option to stop when a 360-degree figure is drawn, it might produce more pleasing results.
Two problems in my opinion. One, you can't save settings! Two, when you go back to the help it resets everything yet the resset button only resets certain parameters.
