Here's some idle entertainment. This is a collection of videos from
the American Physical SSociety, Division of Fluid Dynamics. Scroll
down the page; it goes on and on.

Some of it is stills, but the videos are very cool.

The humming birds! How cool! I have a neighbor that's fed them for
years from a feeder on our property line and attracts a bunch of them
into our Hawthorn tree and even to flowers on a table I am sitting at.
I've seen as many as a dozen at a time. They are like big insects and
make quite a racket buzzing around. Their coloring is diverse and just
beautiful! So to me, the video was most appreciated.
