+-- | A simple Turtle-graphics demonstration for modeling the location of a turtle.
+--
+-- This is based on the code presented by Seth Tisue at the Boston Area Scala
+-- Enthusiasts meeting during his lens talk.
+--
+-- Usage:
+--
+-- > def & forward 10 & down & tColor .~ red & turn (pi/2) & forward 5
+-- Turtle {_tPoint = Point {__x = 5.0, __y = 10.0}
+--        , _tColor = Color {__r = 255, __g = 0, __b = 0}
+--        , _heading = 1.5707963267948966
+--        , _penDown = True}
