Algodoo

the original design was from tbone so i take no credit, i kinda just modded it and beefed it up. THis thing is actually quite hard to use so listen up, hold the right arrow key with the up arrow key until one of the pistons hit the red moving tab, when this happens a small burst of circles will appear, quickly let go of the right arrow key and keep holding up, if you're lucky and did it right the vehicle shall now move along and a tarmac destroying 8m/s modify the power and the shaking by changing the mass of the pistons *works anywhere*+ you can also start it by making it move a little and holding up arrow, it seems artificial though so id prefer the right arrow
