The GEAPPLE PUZZLE is not a stack of balls.
This elegant puzzle initially looks like a stack of cannon balls; however closer inspection reveals that balls have dimples to fit their neighbours and so it is a serious challenge to reassemble the pyramid.
CNC machined in aluminium, it was designed by Andraz Zagyvay and won the Jury 1st prize in the 2013 Nob Yoshigahara Puzzle Design Competition
