Image creates a spirolateral type image for a given number sequence. Line segments are drawn 90 degrees in the counterclockwise direction on a 20x20 grid. Repeating patterns colored in red. Starting point (x,y) - defaults to (10,10) - and number sequence can be passed to the image via a querystring appended to the url i.e. append ?x=7&y=5&s=3,1,6,5,4,2,7,6,4 to the image url and draw that sequence. Default image parameters are equivalent to the query string ?x=13&y=19&s=6,6,18 The timing can be changed by passing t=milliseconds (default=250 is minimum allowed). Have a favorite query string? Share it by adding it to the comments on this image. Thanks for sharing!
