[edit] Conflict with Spirograph page

The webpage for Spirograph states that (paraphrased) spirograph drawings look similar and are based on similar math, but this page states that spirograph drawings look similar but have somewhat different math. Neither is backed by a reference. --Edgriebel 19:15, 8 September 2006 (UTC)

[edit] What are the parameters?

Please describe what the parameters mean, their limits etc. -SharkD 00:41, 1 November 2006 (UTC)

[edit] Diagram and description at odds

The phase shift/ratio diagram and the general description of the curve are at odds. The article states that a parabola is gotten by phase shifts of pi/2, while the diagram shows a parabola at pi/4. -SharkD 20:10, 1 November 2006 (UTC)

[edit] a:b ratios are wrong

November 2006 a & b ratios shouls be inverse through out the whole article. (eg. If the article says a:b=1:2 the graph is actually a:b=2:1) This error is consistent in the whole article.
