Code:

from math import *
from casioplot import *
def hat():
  p=192; q=100
  xp=144; xr=1.5*3.1415927
  yp=56; yr=1; zp=64
  xf=xr/xp; yf=yp/yr; zf=xr/zp
  for y in range(0,192):
    for x in range(0,384):
      set_pixel(x,y)
  for zi in range(-q,q):
    if zi>=-zp and zi<=zp:
      zt=zi*xp/zp; zz=zi
      xl=int(.5+sqrt(xp*xp-zt*zt))
      for xi in range(-xl,xl+1):
        xt=sqrt(xi*xi+zt*zt)*xf; xx=xi
        yy=(sin(xt)+.4*sin(3*xt))*yf
        x1=int(xx+zz+p)
        y1=192-int(yy-zz+q)
        set_pixel(x1,y1,(0,255,0))
        for m in range(y1+1,y1+10):
          set_pixel(x1,m)
      show_screen()

You don't want to see it drawn?

It still shows it being drawn, but a whole section at a time (including hidden line removal) instead of a single point at a time. The main speed increase comes from only blanking 10 pixels below the curve for hidden line removal instead of blanking all the way to the bottom.
