1. About Walter Zorn

"I recently stumbled across a site that contains a small treasure trove of incredibly useful code for Web applications. The site is walterzorn.com, the home of (as you might guess) one Walter Zorn, a software developer and recumbent bicycle enthusiast from Munich, Germany. I found Walter’s site because I was looking for a tool tip system written in JavaScript for my wife’s apparel company Web site and I found Walter’s cross-browser JavaScript library (to see how I used it go here and click on the “Why” link). This is one of the nicest tool tip libraries I’ve seen. It runs under Gecko Browsers (Firefox, Mozilla, Netscape 6+, Galeon and others), IE 5+, Opera 7+, Konqueror, and Safari, and features automatic bubble width, inclusion of any HTML content including formatting, images, breaks, tables, links, etc., and it supports extensions." Web Applications Alert By Mark Gibbs, Network World, September 12, 2007

Walter also offers some other excellent tools that I have yet to use “in anger”. These include an amazing DHTML JavaScript library that implements Drag & Drop for Images and Layers, a JavaScript VectorGraphics library, and a JavaScript Online Function Grapher that can do some impressive math is under development.

Roland,
I am an old friend of Walter, but left for Australia 7 years ago. Walter and I spend weeks discussing recumbents before he built the Kreuzotter. I failed to contact him. Is it true he died? I am devastated. Can you email to me please, have you got details?

3. Advanced DHTML, JavaScript (gualtierozorni.altervista.org)

"WZGrapher is an easy-to-use and small-footprinted Function Graphing and Calculation Program written in C language, with capabilities to plot both cartesian and polar functions. WZGrapher can also be used to graph numerical solution curves of integrals, to solve numerically and to graph ordinary differential equations up to the fifth order, and to calculate value tables (also of ODEs) including the first derivative values."

Demonstration .
mapper.js 2.4 allows you to add automatic area highlighting to image maps on your webpages (inc. export to SVG). It works in all the major browsers - Mozilla Firefox 1.5+, Opera 9+, Safari and IE6+. On older browsers, it can use "jsgraphics" from Walter Zorn (if installed), else it'll degrade and your visitors won't notice a thing.

4. Pure Javascript Martin Browser Fractals By Peter Bromberg (2007)

"I've always had a fascination with fractal geometry. Its funny because I was so disinterested in mathematics that I almost failed 9th grade algebra. But once through college and with the advent of computers and graphics, math took on a whole new light for me. At home we have a coffee-table copy of Benoit Mandelbrot's book on Fractals (Mandelbrot could be considered the "father" of fractals, the Mandelbrot Set is named after him) ... Recently I came across Walter Zorn's Javascript graphics library and was impressed. Essentially he is drawing colored div tags into the browser, each absolutely positioned. No VML, no SVG - it's 100% pure client script, and it works with virtually every browser. The single .JS file is only about 19K, and if you compress it as I did, you can get it down to about 11K - not bad at all. So, I turned my attention back to my Martin Fractals article and decided to adapt the functions to use Zorn's library. ."
