I like the "Whirlygigs quilt"--I think it is cute from charm packs. Pinwheels would also work. Just cut them diagonally in half and sew them together. Easier but not as different as the whirlygigs. There are books for just charm packs if you want to use one of those. I don't know if your library would have it but you could request it. If I knew the name and author I would let you know but I am not at home at the moment.
Piece and blessings,
