This is for the contest of the T shirt, but also it's for me.

I never understood how this machine works, and it burned my imagination.

At first sight the Boulder Mobile it seems to work by brute force: kick the head with the stick club to gain speed. Stop punching tho decrease it.

That's amazing.

How a petrol motor could fit there? An electric one can!
