Python version (put it in a file 'spiral.py' then just run it):

from turtle import *

def spiral():
    reset()
    degrees()
    tracer(0)
    for i in range(40000):
            t = i/100.
            x = .5 * t * cos(t)
            y = .5 * t * sin(t)
            goto(x, y)

if __name__=='__main__':
    spiral()
    # The code below lets the screen update and then waits until you
    # close the window.
    import turtle
    turtle._root.mainloop()
