Sometimes “engineering” is better than run-of-the-mill contemporary sculpture. The marble machine depicted below is created by xeniaguy2 (I could not find out his real name) and it looks like it is something he is making as a “hobby”. Even though it is easily described as a “Rube Goldberg” contraption, it displays a sense of grace and a power of invention that enthralls, intensifying its significance beyond its apparent means.
Also, it is an example of “open source” in the real three dimensional world, since it lays bare its mechanisms and their principles. It shows you how it is doing what it is doing and teaches along the way. (Ironically much of our created environment, before the digital, is “open source”).
So, three cheers for xeniaguy2. I look forward to more installments, as he continues this amazing project.
