This is quite an art, and all the pieces are impressive. The artist/designer in me is partial to the colorful modular shapes. The clean lines of the whole shape made up of smaller lines is very aesthetically pleasing. The engineer in me enjoys the spatial complexity of the jewellery box that encapsulates spatial principles that are both mechanical and organic. And the little boy in me rejoices at the sight of the x-wing, the dog, and the spaceship. I imagine it's very challenging to build them.
