The History
This program was originally written in Basic in the early 1980's for a "Dick Smith System 80" powered by an 8-bit Z80 microprocessor (primitive times, where 32k of RAM was considered good). It was quite clunky, with chunky monotone graphics, and slow, but it worked.
 
In the mid-1990s, as part of an effort to learn AutoLISP, I decided to rewrite the program in lisp so that the resulting “image” or rather drawing (in dwg format) could be printed in high resolution. It was simply called “Spiro.lsp”, (I’ve still got a copy filed away somewhere). This program worked with AutoCAD Release 12, producing high resolution cad drawings. I learned quite a lot about AutoLISP and programming in general (but I certainly wouldn’t call myself expert – far from it).
 
After I retired, I figured I would rewrite the program in Java Script so that it could be run from a web page by anyone anywhere.

 
Understanding Mathematics
As an engineer, mathematics was one of the tools at my disposal that I used in everyday life to get the job done. Remember the days at school when we said, “When are we ever going to use that?” Well, many of those equations and techniques I did use, and the ones that I didn’t use directly, quipped me to do greater things.
 
Don’t shy away from getting understanding, it will equip you for living life. God designed you with an enquiring mind, and He intended us to use that mind to gain understanding and perhaps even understand Him. When He laid out the foundations of the universe, He set out the laws of physics and mathematics. He intended us to explore and understand. Jesus is King.

 
Licence
Images generated from this site for private purposes are free to use as you feel fit without cost. Feel free to share the images with your friends and family, make that coffee mug for your grandmother, a print for a sibling, a t-shirt for your nephew, etc. I only ask that you share this site with friends and family so that others can also have fun exploring the world of mathematics.
 
If you intend to use the product for commercial purposes, such as printing on a t-shirt, mugs etc to sell as a product, or for a business logo, or any other commercial purpose, then I ask that you get in contact with me. A lot of work has gone into making this program and it is only right that money is to be made from this, then the one who has written the software should get a small portion of the proceeds.

 
The Rules
Experiment, explore options, do different things and see what happens, gain understanding, be creative, share it with your friends, but most of all have fun.
