It's indeed hard to impossible to find any good tiling water animation on the internet (surface, not caustics).
That's why I made some video recordings yesterday. I will now try to loop some sequences and make them seamless. More later.
EDIT - arrgh! It's not easy, really! I managed to loop a sequence, made it seamless using elias_t's code. Unfortunately in nature it's virtually impossible to find some waves with an equal brightness and contrast etc. over the whole frame width. There are also highly significant details. These things make the tiling very obvious when watched from distance, no matter if they tile seamlessy.
Furthermore, if the sequence wasn't recorded 100% vertically in topdown view (eg. from a brigde) then the angle of view will make it look strange when rotated (or watched from) 90 or 270 degrees.
It really isn't easy. By mistake I displayed the animated waves as a normalmap - wow that was weird. Try this at home: animated normalmaps - impressive.
