The inventor of the Pluto Platter, better known as the Frisbee, died a few days ago. (I read about it in the dead tree LA Times; the link is to a paper that was famous at one time.) I remember calling frisbees 'flying saucers' before I knew their official name. Fred Morrison invented them in 1957, appropriately in the rocketpunk era, hence this wonderful period image.
In honor of the surprisingly graceful game of stoners' football that this technology made possible, consider this an open thread, a handy home for spin-off discussions that don't quite fit previous posts.
