Fibonacci Sequence: "A series of numbers in which each number ( Fibonacci number ) is the sum of the two preceding numbers. The simplest is the series 1, 1, 2, 3, 5, 8, etc." Press space to generate the numbers. It is done in only a fraction of a second, even without turbo mode.
Simple to code, but I thought it was a neat idea. Be prepared for maybe a few more projects like this in the future.
