But it is theatre.
A single £0.01 Zener diode can generate vastly more guaranteed (by quantum mechanics!) randomness, without all the possibility of failure, entropy leaking etc.
Yes it is much more cool to look at than a zener diode, but it is still a source of physical entropy. And one could argue that a whole bunch of chaotic pendulums are more resilient to failure than a single diode.
