Columbus Cubes

 

  

Columbus Cubes are one of my favourite.  Quite satisfying to make and stack.  I keep meaning to do more with them.  I found these in a book by David Mitchell (his website is well worth a visit!)  His page about the Columbus cubes is here.  There is also a video on YouTube on how to make them https://www.youtube.com/watch?v=6u-1a1UFj_k.  There's even a kusudama to make with them.  That's on the list to do in the future. It has now been done.
