I am an author of the papers referred to above on the axis-parallel case, and I am currently writing a paper for American Mathematical Monthly on the status of this problem. I would like to study and possibly cite your work, but all the links appear to be dead? My take on working "non-axis parallel" has mainly been that the original problem was sufficiently hard, but I've also been concerned about the issue of elasticity of the models. I mean: there should be many configurations where there is no mathematically exact way of connecting the bricks, but that the building could still be realized by real bricks since they must be slightly elastic. But then we have left the realm of mathematics and entered material science. If you always have configurations then can be "wiggled" and identify those that can be wiggled into another, then I agree it is math again. Best, Søren Eilers eilers@math.ku.dk
