trigonometry

Busted out the 9th grade math to do proper radians. In some of the previous examples, I was varying the angle of each element based on parameters of the color, but I wasn’t doing by proper trigonometry; instead, I was just using an offset one way across the bottom, and the opposite offset across the top. This limits the angle to plus or minus 45 degrees, and won’t line up with a circle. This new routine allows proper 360 degree rotation. So now I can play with making each shape-mark more of a glyph. Depending on parameters, they look like arrows, tees, dials, sputniks, etc. And each mark is representative of the color information with which it’s drawn.
