Wow, what a reputation Keith Richards has. I tried him 1st as well. I guess when you shoot cocaine into your eyeballs for fun, it kinda sticks with you.
I remember seeing Richards in Jean Luc Godard's documentary "Sympathy For The Devil," (aka "1+1," which was Godard's version) and thinking "Jeez--Keith is not long for this world." That was 1970.
Tried like thirty different variations of "influencer/YouTube personality/content creator" for Charizard and company. Feels like all the internet personalities have dumb names like that.
Semaphore communication uses visual signals such as lights, flags or movable arms. There is a pretty complicated semaphore light system in marine navigation so a captain can telegraph the vessel status or activity. Traffic signals (red/yellow/white) and railroad semaphores are other examples.
