What is this? This is often the first question you hear when someone sees this device for the first time. Well, that's a good question, and we have a simple answer: the most unnecessary machine of all time!

But there's also the question of what you can do with it? Absolutely nothing: the device is completely useless. At best, it's a gift for someone who already has everything - except for a pointless machine.

In internet circles and among the classically educated elite, one might refer to the function as a Sisyphean task. In Greek mythology, Sisyphus was punished for his misdeeds by being forced to roll a stone up a hill for eternity. However, as soon as he reached the top, the stone would roll back down, making his work seem endless and futile.

Beta students and tech-savvy hobbyists will enjoy building this product, and they will surely appreciate the simple technology behind this design.
