It sounds like you might be asking about a sampler quilt. If so, the BOOM threads in quiltboard can help guide you to lots of sites with free patterns.
I have seen a quilter in this board who works with other quilters. They pick a photograph, divide the photo into sections and let each quilter reproduce one of the sections. After each section is completed the quilt is assembled. Is that what you're thinking about doing? I have no idea what that particular style is called.
