This week’s widget is, as suggested in an earlier post, a result of exploring the attic. Years ago I posted a simple program that uses an iterative loop to create a huge number of lovely looking patterns.<\/p>\n
Unfortunately that code was written in Java, so it no longer runs on the Web. So this evening I reimplemented it in Javascript. It lives again!<\/p>\n
As you move your mouse around, vast numbers of patterns are displayed. Some mouse positions produce beautifully symmetric results, others just result in a mess.<\/p>\n
The core code is two lines that look something like the following, which get repeated 8000 times to make the point (x,y) trace out a pattern. The loop starts with x=y=t=0, and (X,Y) is your cursor position:<\/p>\n
\nt += ( pow(x*x*Y, X) + pow(y*y\/Y, Y) ) \/ 200;\nlineTo(x += cos(t), y += sin(t));\n<\/pre>\n<\/blockquote>\nI love the emergent nature of it all — how a multitude of patterns can arise from something so simple.<\/p>\n
