Bethany Renolds has several books out on the Stack and Whck techniques. She has the traditional star, triangles, fan and rectangles.....In the tutorial section, Cutbuns did a wonderful tutorial on the One Block Wonder. It is a variation of the S&W but uses equilateral triangles for a great quilt top. Another pattern in a similar style is the 4 Patch Posy that is 4 squares or triangles that form a neat design. Look at the pictures in the Picture section to see examples of all these quilts listed by names.
