If I wasn't (and I wasn't) annoyed by the 20 questions style of o.p. Unless ticking people off was the intent?? I am annoyed now by the coy reveal. WTH? Why should anyone recognize a one off class project except it's designer/fabricator? It's like 46 years later, o.p. is still as socially clumsy as they were back in Engineering School. This could have gone so differently. A life well lived is impressive only to a point. Billions do it. Next time you feel the need to share, do it like a mature person without all the intrigue.
