You may want to consider rotating the texture around a centre some distance 
above or below your plane, so the same texture comes round again once every 
cycle. So if you use 'rotate 360*clock*x  translate <0,100,-20>' the first 
and last frame should turn out the same.

If the rotational centre you use for the texture is held above the camera 
then it should look like the waves are coming towards you. If you've got 
other items in the scene and you want it to look like you're moving over the 
surface you can move the totational centre of the texture along to keep pace 
with the camera while still rotating the texture. This should then look like 
a constantly changing seascape with waves approaching you but it should get 
over the cycle issue.

Hope I've explained this clearly.
