I've seen quilts that used the OBW shape (equilateral triangles) with different fabrics, so it's not really a OBW but is sewn together in the same fashion. The tricky part is getting the fabrics in the right positions to. You can also use the kaleidoscope block with 8 triangles sewn together (with triangles on each corner to square it off). I'm looking forward to seeing what you come up with.
