The tortoise library currently provides following methods (coordinates and distances are relative to the viewbox of the SVG):
(dom,id): returns a tortoise object which uses

0will disable the auto draw); call
draw()to render remaining movements,
setPosition(x,y): the turtle jumps to position
forward(distance): the tortoise moves by the specified
right(angle): the tortoise turns clockwise from
left(angle): the tortoise turns counter clockwise from
setColorRGB(r,g,b): sets the color of the pen following the RGB color model,
setColorHSL(h,s,l): sets the color of the pen following the HSL color model, (
h: 0 - 360;
l: 0 - 100%),
draw(): draws remaining movements,
clear(): erase the drawing area and also resets the internal settings (coordinates, angle, color…).
