Just click on the green flag. Resist the temptation to immediately switch to Turbo. Enjoy the fruits of the coded mathematical weaver as it traces a delicate, airy, parametric fabric. Once you've seen how the fabric is woven, then swicth to Turbo.
Project idea taken from: The Magic Machine: A Handbook of Computer Sorcery A. K. Dewdney Chapter 24 - The Invisible Professor Miller's Madness - page 276 Stanley S. Miller Parametric Equations: x = sin(0.99t) – 0.7cos(3.01t) y = cos(1.01t) + 0.1sin(15.03t) A detailed explanation of how the code is constructed can be had at www.scratch-blog.com
