Marathon Calculator

A rather intricate technique that uses the marathon engine as a binary calculator to add two numbers. Its limit is 31 (as the total), and because the actual mechanism is shown, there's a long walk between the calculator and the answer... but it's amazing what you can do when you're free for the summer. (Really, really detailed explanation.) Definitely worth a look if you're curious about how far the engine can be pushed for non-standard tasks.
