                        SpiroGraphics Version 1.0

Hows it going?  You have downloaded SpiroGraphics version 1.0. This is the 

first version of the software, so I expect it might have some bugs in it.

As of right now, it seems to work pretty good. Later versions will of course

have more functions.  The only purpose of this software is for your enjoyment,

which I hope will be considerable. Acutally this software grew out of a 

project I had for myself, which was to graph certain mathmatical possibilities.

Trying to find a simple and reasonable way to explain Debrogly wavelengths was

how this started. This possible solution that I came up with involved writing

an algorithm that simply revolved the radius of one circle around another. On 

further explanation, try imagining the way the earth revolves around the sun,

and how the moon revolves around the earth at the same time. If you could

plot the track of the moon in its motion you would find that it produces a

track that can approximately be reproduced with SpiroGraphics. A radius

ratio of about 93,000,000 to 250,000 gives an answer of about 372 to 1,

with 12 revolutions of the moon for every one of the earths. Unfortunately

that ration of 372 to 1 is beyond the scope of this version of SpiroGraphics,

but I hope that you get the idea of what the software is doing when you 

change the variables. Many combinations of variables can be used to produce

a wide variety of colors and figures. Screen pictures can be saved as *.spg

files for later study. Foreground and Background colors are changeable in 

256 colors. Connecting the plotted points with lines sometimes gives better

understanding of the graphs and that option is available. Some examples have

been included built in to the menu to help get you started faster in under-

standing what the possibilities are. It is my desire that this software

be redistributed as widely as possible, so pass it on. There is a request 

for registration with a low fee of $5.00. I realize that 98% of shareware

users fail to register and pay the fee. However, I'm hoping that a comb-

ination of low price and pity for a poor student working his way through

college will induce at least a few of you to send me the registration fee.

You can also send suggestions and comments to that same address and I will

appreciate them considerably. If for some reason, anyone would actually

like to call me, the phone number is 205-442-5323. There will be at least 

one more version of SpiroGraphics, where it gets a Multiple Document Inter-

face and has more functions and better Help. Thanks for trying the software

and I hope you get at least a little enjoyment from it.
