this spiral is given by parametric equations based originally on theta = t r = t/40 or something like that, except for all occurences of the parameter t replaced with a function which causes the total translational speed to be constant. I tested it with another sprite put a constant amount ahead of the drawing sprite in terms of t and measuring the distance. This is useful because the points don't get further apart when the circle gets wider. it is better for filling up an image with dots so that the quality always stays the same. I made a similar project long ago, however it is not fully parametric.
