yes, interesting and pretty your references. (I do have a nice i pod touch app for fractals, live, interactive; as well as many graphing calculators on i pod touch)
By the way, I find the Lulu books a bit dear money wise in this day and age, and the Lulu book 'J for C programers' shed two pages quickly. Also, I just found out to my disappointment that J won't handle relatively simple definite integrals like 1/x^1.001 from 1 to infinity thanks ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
