The Brachistochrone Curve is the mathematical "curve of fastest descent." It is the quickest way for an object to get from point A to a lower point B that is not directly underneath A. I thought it would be neat to be able to watch this phenomenon in real life, rather that just simulations online... so I made one. The inspiration for this piece was my high school math teacher, who I gifted this to for use in his future classes.
