The Cube Tree,
When I discovered that 3 LEGO parts made a perfect cube (one 2x2 plate, one 2x2 brick and one 2x2 tile) I started with the idea to create a large cube of cubes.
The idea was born. I made several designs in LDD.
A must was that the base was not larger than the top of the loudspeakers I have (B&W DM16, made in the 1980-ish)
The design of 3x3x3 cubes was larger than the top of the loudspeakers, so I created *The Cube Tree*
In total 40 *open* cubes supported by transparant plates (1x1) and bricks (1x1) are used in this.
