they won't let you do it at most pools (so do it at the end of sesh when you are leaving anyways) but doing combos on the diving board is rad. busting little 360s or backflips on the board before your tricks is a gnarly element to try.
and for the ultimate diving board, check this pic.
it goes from 7m at high tide to to 10m at low tide. and there are phosphorescents there at night. there is also a rope swing of equal height there. and a dope ass 10 man hammock. yes, the west coast does slay the east.
indoor diving boards are fun an all, but i just regard them as training for high diving off cliffs. and something cool i've done before is having a trampoline into the ocean. that was pretty sweet.
i'm moving into a new house with an inground pool pretty soon (the pool probably won't be operational until next summer though, work to be done, it can also be skated, awesome) and i also have two trampolines to combo it up with. i'm hoping to combo in a roof drop and patio transfer as well.
rope swings are way rad too. its killer when you swing them around in a big ellipse, you can get insane types of corks like that.
i kinda feel sorry for the lifeguards when i go to the pool. my crew is pretty burly with our tricks and we like to play horse too. plus when we leave we like to go out with style and usually do some sort of stunt to get us kicked out... the stories i could tell you. not to mention we usually sneak in. another reason why cliff jumping is better, it's free. though often illegal in some spots. c'est la vie...
