(...) I'm glad you like the book. Yeah, that half-peg was a problem for at least one of our tech reviewers (beta test team). If we do another book I'll probably start using inset boxes that list how many of each piece per step. That way if you (...) (25 years ago, 31-Dec-99, to lugnet.technic, lugnet.robotics)

I thought I saw somewhere that they used RayDream, an inexpensive modeling/rendering package. The parts were custom made so that black on black beams render well. Notice the small bevel on top of the beams. Ingenious! Hope I'm not stepping on Dave's (...) (25 years ago, 31-Dec-99, to lugnet.technic, lugnet.robotics)

I'm by no means a legal expert, and perhaps I'm being a bit paranoid, but I don't believe its quite that simple. First, I wouldn't trust anything I wrote to actually hold up in a court of law, so I'd need to hire an attorney to write it. One way (...) (25 years ago, 2-Jan-00, to lugnet.technic, lugnet.robotics)
