Hi there,
Just looking for a little advice. I'm working on a 2D game and presently have just a plain blue tile for the water. I then discovered this little video:

If you watch a few seconds in, you'll see some pictures of the water and what appears to be random waves placed across it.

Any suggestions how this may have been achieved?

Cheers

just looks like an animated texture to me.
