Ravelry: Moorish Mosaic Afghan pattern by Lisa Naskrent. Started this years ago and I will finish someday. This is beautiful. The yarn used in the pattern is no longer made but there could be many substitutions.
I am going to try making this hat for my daughter, Maureen, along with the matching scarf. The pattern is actually from Ravelry and there is a link to it on All About Ami - Urban Jungle Slouchy Beanie but the photos on All About Ami are especially pretty.
