Value of (0,-1) is located at top of circle? Kind of a major error
Dave (**)
Um... counter-clockwise produces a positive θ/degree growth. You have it backwards. You may want to fix that huge error...

Sorta odd that the circle is top side down. And I wish it could do rad as fractions of pi.

Got a little better. Now can do anything under one inch. Can you add trackball support to move the sliders trying to hit .3574 with your finger is imp
