# Dave's Creature

• after this tweet:
and this processing code:

I made a DrawBot/Python translation:

``````import math
n = 720
l = 350
twm = math.pi/20

def mapValue(value, start1, stop1, start2, stop2):
p = 1.0*(value-start1) / (stop1 - start1)
return start2 + p*(stop2 - start2)

def spiral(q, R, nt):
path = BezierPath()
origin = width()*.5, height()*.5
path.moveTo(origin)
for i in range(n):
qq = 1.0*i/(n-1)
r = mapValue(math.cos(2*math.pi*qq), 1, -1, 0, R)*math.sqrt(qq)
th = nt*2*math.pi*qq - 4*2*math.pi*t - q
x = r*math.cos(th)
y = -l*qq + r*math.sin(th)

tw = twm*math.sin(2*math.pi*t - math.pi*qq)

xx = x*math.cos(tw) + y*math.sin(tw)
yy = y*math.cos(tw) - x*math.sin(tw)

path.lineTo((origin[0]+xx, origin[1]+yy))

path.endPath()
drawPath(path)

N = 9
frames = 60

for f in range(frames):
newPage(1000, 1000)
frameDuration(1/30)
fill(1)
rect(0, 0, width(), height())
t = 1.0*f/frames
for i in range(N):
R = 42
m = mapValue(math.sin(2*math.pi*t), -1, 1, 0, 1)
nt = 6+6*m
save()
stroke(.5)
fill(None)
strokeWidth(1)
rotate(360.0*i/N, (width()*.5, height()*.5))
spiral(2*math.pi*i/N, R, nt);
restore()
saveImage('davesCreature.gif')
``````

One might find mapValue an interesting function featured natively in processing:
