I sure like your 'handle,' and I was just musing on asymptotes the other day, wondering if frequency fences are the 'same as'....  Also, what do Pi and POTUS have in common? Lots, apparently, with markers at March 14 (3.14), and 3:14 on the watch... The vase thing is interesting. Makes me think of the 'ting,' a Chinese ceremonial (exclusively?) vessel for water...out of their Wu shamanic era of the distant past, if I recall correctly.
