If you think about it, it has I haven't seen your program, but I can tell, that it surely has.
First of all, you've learned something, while programming it (or RElearned - RElearning is the mother of science)
Second, you had the ability to show it here, and to hears something like:
"Wow, that's pretty cool, and definitely has no use!" or "Oh, come on - It has a wide range of usage".
So there IS no useless thing. If Kohji was making this contes understanding that, he's definitely the winner!
