A year or so ago walking along the beach I saw a kid who was overweight, alabaster white, wore glasses, etc. quite unlike the "usual" beach crowd. However, he had the most spectacular sandcastle =complex= on the beach. Ah, baby nerds... our kind will indeed continue into the next generation. I had to offer him words of encouragement.

However, telling that story inspired me. I went back to the beach with some tools and did a proof-of-concept of a flying buttress in a sand castle.

No computers on the beach, though. The sand is just too much for it. Though a pocket-PC in a ziplock bag might be in my future...
