Here's an animation of a great knot,
the Constrictor Hitch. It's easy to tie and it doesn't
want to let go. The Double Constrictoris even
more tenacious. Take two turns around the item(s)
first. As long as the knot is against a smooth
surface, the knot will hold. If it's suspended in
midair like in a gap between two bamboos, it will
eventually loosen, so be careful.
I made the animation to teach myself visually how
to tie one flopped over on the left end of a bamboo; I
had a hard time visualizing it. "Right" and "Left"
refer to the direction of the first turn, toward the
right and back, or towards the left and back. It's
completely arbitrary but it works for me.

Craig,
Concerning the constrictor knot demo on your web site, here is
another way to tie one, easily and quickly. The knot is tied
in 'mid-air' and can then be slid over the end of something.
I use this regularly for quickly whipping the end of a line.
First make a loop:
/ \
/ \
/ \
/ \
( )
\ /
under -> \ / <- over
---------- /
\ ________
Holding each of the standing ends in the fingers of each hand,
stick your left thumb up through the loop from below and
your right thumb down through the loop from above.
Rotate your right hand in the direction you would tighten
a screw, allowing the lines to cross between thumbs.
Bring the ends of your thumbs together and slide the knot off
the right thumb and onto the left thumb. Voila!
