Noticed this on Boingboing: "Introducing GameByEmail's Dice-O-Matic. Made from Legos, a USB camera, and a bit of software, it's a home-grown, dice-rolling monster. Don't let it's rickety looks deceive you; this puppy can easily crank out the 20,000 (...) (20 years ago, 6-Dec-05, to lugnet.robotics)

(...) POVray worked hard for those images. Shrinking them is telling it that you have no respect for its work. You never know, all future renders might turn out wrong because it is mad. ;) Tim (20 years ago, 6-Dec-05, to lugnet.cad.dev.org.ldraw, FTX)

(...) Actually, what you need to do is *skew* the 1-4edge. Literally deform it, so it stretches along the edge of the stud3 cylinder. If you turn it, it will no longer intersect the surface of the cylinder -- the edge will disappear inside the (...) (20 years ago, 6-Dec-05, to lugnet.cad, FTX)

(...) While I agree with both of you, we should keep in mind that Orion said that this is a postnuke problem.
