SCHUHAJ – I Madeup Life
I looked at what had existed so far, and upon seeing Corey’s thought on making a double helix, I wanted to make one.
First I needed to make a spiral,
for i to 5
for t in 0,30..360
x = 10 * cos t
y = 10 * sin t
z = 0.1 * (360 * i + t)
moveto x, y, z
end
end
Then I needed to be able to reverse down that same spiral to the beginning to start the second spiral.
for j in 4,3..0
for s in 360,330..0
x = 10 * cos s
y = 10 * sin s
z = 0.1 * (360 * j + s)
moveto x, y, z
end
end
Then I jumped over and made the second spiral.
for i through 4
for t in 0,30..360
x = 10 * cos (t + 180)
y = 10 * sin (t + 180)
z = 0.1 * (360 * i + t)
moveto x, y, z
end
end
I didn’t bother figuring out the reversing of this spiral, realizing I was going to alter my approach.
I knew I was going to be drawing at least some of the lines twice, so I altered the approach to a four step process:
Draw part of the first helix. Jump across to the other helix. Draw part of the second helix. Jump across to the other helix.
helix = 0
hc = 180
d = 10
for i through 4
for t in 0,30..360
if helix == 0
x = d * cos t
y = d * sin t
z = 0.1 * (360 * i + t)
moveto x, y, z
x = d * cos (t+hc)
y = d * sin (t+hc)
moveto x, y, z
helix = 1
else
x = d * cos (t + hc)
y = d * sin (t + hc)
z = 0.1 * (360 * i + t)
moveto x, y, z
x = d * cos t
y = d * sin t
moveto x, y, z
helix = 0
end
end
end
Once I completed that, I was at the top, and just needed to make my way back down while drawing the gaps in each helix, only duplicating the jumps across the helixes.
BOOM!
Final code:
helix = 0
hc = 180
d = 10
for i through 4
for t in 0,30..360
if helix == 0
x = d * cos t
y = d * sin t
z = 0.1 * (360 * i + t)
moveto x, y, z
x = d * cos (t+hc)
y = d * sin (t+hc)
moveto x, y, z
helix = 1
else
x = d * cos (t + hc)
y = d * sin (t + hc)
z = 0.1 * (360 * i + t)
moveto x, y, z
x = d * cos t
y = d * sin t
moveto x, y, z
helix = 0
end
end
end
helix = 0
for i in 4,3..0
for t in 360,330..0
if helix == 0
x = d * cos t
y = d * sin t
z = 0.1 * (360 * i + t)
moveto x, y, z
x = d * cos (t+hc)
y = d * sin (t+hc)
moveto x, y, z
helix = 1
else
x = d * cos (t + hc)
y = d * sin (t + hc)
z = 0.1 * (360 * i + t)
moveto x, y, z
x = d * cos t
y = d * sin t
moveto x, y, z
helix = 0
end
end
end

The only hurdles I faced were my limitations in geometry. I had to walk away from the computer many times…
The only bugs I faced were:
Hitting “fit” button multiple times would make it switch between actually fitting, a blank screen, and a screen with strange dark pixels
Adding comments will make the code not work. (Particularly after an else statement and on its own line.)
I kept playing with the program making stupid things…
The useless hammer:
Worthwhile hammer:
