doable with jQuery? if so, how (tutorial?)

hi guys,

i try to rework my webpage and i woudl like to have a nice animation on the bottom corner...
so, the first part i already got working (divers blowing bubbles)
see@ luke2000.lu.funpic.de

now i want to add animation to the legs of the divers (moving up and down)

therefore i would like to split the divers in three parts
the body, the leg, and the fins

the body won't move (yet - later it should move around a bit - but the whole diver!)
the legt should rotate up and down - the image needs to be rotated.
therefore i need to calculate the new position of the fins (they do not need to be rotated) but they need to keep aligned with the leg (a diver should not loose his legs ;) )

i just guess i need sin to calculate the degrees and the new position of the leg...
but is it possible to rotate images with jquery, the way i need it?

thanks in advance
