I did an umbrella recently and had lots of comments when I posted it on its side.. I thought about it and considered that I could do something similar but like a radio dish or an old fashioned microphone. I also had some limestone to work with and thought this would be an ideal focus for the dish. I must admit I do feel much of what is transmitted on TV, the internet and on other media platforms is mostly junk and that resonates nicely with my dish. There is a kernel of value and the stone part sort of reflects this.
