What should I do with the waves?

Hint 1 of 9:

Those waves look a bit choppy.

Hint 2 of 9:

They even look a bit unnatural.

Hint 3 of 9:

Real waves would flow together a bit more smoothly than the ones here.

Hint 4 of 9:

That's what you need to do -- make the waves flow together smoothly.

Hint 5 of 9:

Try moving your cursor over the waves.  Notice that they stop?

Hint 6 of 9:

And if you click on a section of waves (they're in a 3x3 grid), it will
advance one step.

Hint 7 of 9:

All you need to do is position the waves so that they're all in sync with
each other.

Hint 8 of 9:

The three squares in a row should flow together, and when a wave leaves one
row, it should start to appear on the next row.

Hint 9 of 9:

I recommend working just on one column first.  Once you think you have the
flow from row to row established, you can make the waves in the other columns
match the first one.
