A very nice optical illusion Somewhat disturbing : how can all these perfectly square LEGO bricks appear to be not so square anymore ? Did I buy bad quality bricks ? Or didn't I ? This illusion is not my own design : it's one of the designs from Corey Sanders. For several designs he has instructions available on his website : www.brickitgood.com Thanks for sharing these out Corey ! Jan-Willem elmo_jws@hotmail.com
