Also known as KWJ

I've been a Tcl'er since the days of Tcl4.x, and in a previous existence wrote a fairly serious scientific data browser using Tcl/Tk. I've long wanted to contribute to the tcl community.

Some of my heroes are Arjen Markus, Richard Suchenwirth, Steve Landers and others too numerous to mention.

I've recently completed work on Ulam Spirals. The following pages contain this work.

Primal Screens, Primal Screens— Part Two and New Prime Number Browser

A fourth page addresses the question of whether there is a formula which produces large sets of Prime Numbers. Monster Prime Predicting Formula
