Think I've seen something like that. They manage rather interesting  
and subtle tricks with them. (Found that while looking up how to make  
a vortex ring generator like the one I saw at Maker Faire.)

Actually, I had seen some of the dolphins at Sea World of San Antonio 
make bubble rings in 1999.  You really couldn't see if they were playing 
with it or not because there was no underwater viewing window there, but 
you could see the rings rising to the surface.  The next year some of 
the dolphins were moved to Discovery Cove in Florida.  Maybe they were 
the dolphins from San Antonio or learned it from them.


Interesting to see the rings moving any direction other than up.  The 
triumph of surface tension over buoyancy.  Must have taken the dolphins 
a lot of practice to be able to do stuff like that.


Yes, I'm back.  Very busy at the moment, but my schedule will be freeing 
up in a couple of months.  Hope to have some Brin related art to share 
soon after.
