But computers are certainly capable of producing them if you only know how to tell them to; a simple program could be written to do a line spiral (I'm not sure a program to produce a to tone spiral would be so simple, it's at least not obvious how that would be done). A graphing calculator could easily generate one, and since WolframAlpha is more than a calculator will ever hope to be, it can also be used to generate one by asking it to plot a linear function (as in a first degree polynomial of one variable) in polar coordinates, though all that other useful information included with the plot sort of ruins the spiral's potential as an image: http://www.wolframalpha.com/input/?i=polar+plot+t%3Dr%2B1<br />In essence what you did was construct a physical equivalent of the algorithm needed to produce a line spiral, which probably works as well as you need it to.<br /><br />For what it's worth, the same process described for the two tone spiral in this post can also produce a line spiral if you start with a line instead of the two tones. Of course, drawing lines in GIMP isn't a straightforward as one might hope, you first need to set up a path and then stroke the path.<br /><br />Flying cars OTOH... classic example of the unfortunately tremendous difference between the ease of imagination and the difficulty (or even impossibility) of implementation.dreamer.redeemerhttps://www.blogger.com/profile/00362667970312901350noreply@blogger.comtag:blogger.com,1999:blog-2920206756348312083.post-3720001495249216622012-06-18T05:00:35.792-06:002012-06-18T05:00:35.792-06:00I wish I could draw a simple line spiral.
