I, unfortunately, don't have a good picture, but Quilts, Quilts and
More Quilts (the sequel to Quilts, Quilts, Quilts) includes a quilt called "Interlocked Squares". I think it's interesting enough that it wouldn't look "cute" even with pinks. I, unfortunately, couldn't find a made up quilt in the pattern on the internet that includes only 2 fabrics. Someone made a multi-fabric version here:

This is a VERY easy quilt but looks amazing. I made it up in a rainbow print with a black, and it was great. The book I mentioned is a classic and is probably available in most, if not all libraries.
