moving water...

Howdy folks,

On the idea of moving water, has anyone thought about using "wave 
generators" on their tanks???  I have used these before on reef tanks and 
they are vey nice.  They have a switch that turns on and off the powerheads 
to imitate the surge and retreat of the water during wave action.  This 
might prevent the "crooked growing plants" that develop from having the 
powerhead pointed at them continously.  Another though i had was to use some 
sort of device on the return of the powerhead that would swivel back and 
forth would prevent the powerhead from blasting one area all of the 
time...but I have no idea how to fabricate one at the moment (Damnit Jim, I 
am a doctor...not an engineer...hehehe).
