Please see detailed explanation: [url]http://en.wikipedia.org/wiki/Arnold's_cat_map[/url] With this demonstration one can get any kinds of linear maps (using [i]a,b,c sliders[/i]), see the map of selected point ([i]"Map of point#"[/i] slider), change amount of points ("[i]size"[/i] slider) and set classic Arnold's map ([i]"Classic"[/i] button).
Tip: After download one can change cat's face, just [i]set visible yellow and blue points and poly1[/i] (^_^) How do you think, why there is no "Previous" button, only "Next"?
