august 2001: yup, 1000. 1000 blue and yellow things. and there are plenty more where these came from. interesting to see the round shape used in the seattle convention centre moc by (name escapes me now). very impressive building.
Of course it is logically. Lego is made out of plastic, even if it's pretty hard it isn't a constant material. In such a big ring out of 2x1 pieces that's no problem + if you do ring, you have the same small stress on all pieces, so it gives you a perfect circle.
Well done! I have seen something similar before, but this one's also pretty good :D
