I think this is possible on almost every computer, but I'm having a very hard time completing it on the computer I'm currently using. (Which is a lot faster than the one I used before). It is definitaly possible within 10 seconds, but on really fast computers the finish disappears in less than 10 seconds.

This is too hard, anyway.
