Getting back to the Shipper’s Dilemma.
Make a 3x3x3 matrix to use as a test setup.
Make an array of pseudo pieces to fill that area.
Display adding the pieces in, one by one in a isometric layout.
Show a counter for passes.
Show a time stamp for beginning to end.
Have a stop button which stops everything and changes to a Go button.
Stop on success.
Pieces are chosen, and rotation applied based on a random number. Use an incremented seed.
After success do this again, but bigger.
