The Most Beautiful Machine, 2003:
"The Most Beautiful Machine" is an idea of Claude E. Shannon, who died in 2001. His "Mathematical Theory of Communication" is the fundament of the digital machine. It's a communication based on the functions ON and OFF.
In this special case the observers are supposed to push the ON button. After a while the lid of the trunk opens, a hand comes out and turns off the machine. The trunk closes - that's it!.
