Appearing image when starting Adobe Photoshop CS 1

[FaaipDeOaid]

When you start Adobe Photoshop CS there appears a nice image of (bird) feather(s). If you look carefully on image you can see parallele lines (green, blue, ...) It seems that that lines follow the image itself. Some of them are hatched.
Does anyone know how to do this in photoshop? This parallel (hatched) lines, without drawing one by one? Without copy/paste?
I would really appreciate any tip.
