Anne Lazenby is the designer behind BeadDiagrams where she shares free and original bead tutorials. One tutorial I really liked is this reversible cuboid inspired design tutorial which has cascading "cubes". 
 
Click on the diagrammatic tutorial to see an enlarged image. Anne also provides a PDF download - scroll down to the bottom for the link.

She calls this her Ophelia design.  Anne recently started a Youtube channel. You can get the video form of the tutorial there.
