craftgrrl | Looking for a Crochet Pattern

Hi all,

I started an afghan for my husband a year or two ago, and I'm ready to start working on it again. But I've lost the pattern!

It's one I found online, the afghan is a shell pattern and the original pattern's picture had it done up in black with many brights; hot pink, yellow, blue etc. If I remember right, the afghan was thrown over a chair, there may have even been a guitar in the picture.

The name of the pattern was made up to believe this particular pattern was pizzaz-ier then any other, I THINK heh. Can anyone help?

EDIT: The color/shell pattern was laid out in such a way that the rows made "waves" of color, a back and forth sort of movement....
