These two patterns came to mind when I read your discription.
Shooting Star - I found this on quilterscache.com/S/ShootingStar Block.
The other pattern is on HGTV. The quickest way to find this for me was to type in "Moorish Four-Patch Quilt" in the http line. Be sure to use the quotes and I went right to the site. Scroll down to Figure H. It's small but it's an interesting design.
Hope this helps. :D
