Turtle state values (can plug into a parameter):
 * X, Y – Zeros for each are at center screen. Negative values are left and down; positive values are right and up.
 * Heading – Zero is pointed up. Heading is in degrees clockwise.
 * Angles are degrees from 0 to 360 (for larger values and smaller values all multiples of 360 are subtracted or added to get the value into the range 0..360).
 * Examples: 90 means a right angle (90 degrees), clockwise; –30 means a 30-degree angle, counterclockwise
