Rules
Zoom MUST be between 0.15 to 0.2 (most optimal is 0.18)
DON'T MESS WITH ANYTHING WITHIN THE STICKMAN (unless you're changing the color)
DON'T MESS WITH ANYTHING WITHIN THE STICKMAN (unless you're changing the color)
After recording, prees '1' to see the actual length (a divided by 2 = b)
"Wait, so they didn't use the actual measurements???" Yes, they didn't!

Additionals
you can modify it a bit to your liking (anything but the stickman)
you can also experiment with the sky color

That's it. Enjoy!
