Algodoo

Sometimes, forging metal with a hammer and anvil won't cut it.
That's what this machine is for. left and right arrow keys moves
the trolley, the up and down arrow keys adjust the table height, and the
F button activates the piston. Reposting this IS permited. However, you
ARE give me the credit. Even if you modified it, you WILL give me some credit
on the idea and orignal contruction on the behalf of this machine.
