Random cool thing from the Internets:

It’s a very, very simple browser game.  Also very, very pretty, and very, very addictive.  I wholeheartedly recommend it to anyone who feels like he isn’t wasting enough time.  Also anyone who likes dolphins.

Gameplay hint (that it took me far too long to figure out): You can chain jumps together.  So long as you get a “Nice Entry” (and you get out of the water again in a reasonable amount of time), your next jump counts as part of your last jump, and you retain all the speed you’ve gathered.  Do this a few times and you can jump *high*.
