This is Arthur. He found this neat little round blue-and-grey thing in the box of bits this evening. He copied it and made a Millenium Falcon.
The trick to this round technique is the 1×1 with studs on all 4 sides (the four white bricks), and the 1×1 with Technic hole (the four grey bricks – 2 are on their sides and 2 are upright hidden under the angle brackety thing. Plus of course the magic blue Cheese slopes.
