ok guys a though one, lol

Can anyone give a rundown tutorial on this again? with a little more detail? I tried it myself and got the basic idea, but it was uuuuugliiiiiiiee, i think my effects might have been off a little, my height map maybe could have used some work, at first i used the gaussian blue method for the height map but that came out like crap, then I used the relfective gradient for teh height map before i used the perspective transform and then aplied the wave filter to my rectangle. This worked much better but still very ugly. i'm thinkin my texture really wasn't right. hmm...i guess i can try again but a more detailed tutorial would be nice.
