After spending several hours wiring up a few customers to our network [1], Smirk and I ended up at Denny's [2] (funny how no one ever sets out to go to Denny's, but inevitably end up there) and the topic of Coral Castle [3] and how Edward Leedskalnin [4], weighing all of a 100 pounds, could build such a structure by himself (where some of the blocks used weigh as much as nine tons).
I mentioned to Smirk that I came across a possible technique which basically uses leverage, counter weights and pivot points but that I didn't remember the actual details. So imagine my surprise when I found a video of the technique [5] while reading Jason Kottke's blog [6].
It was then that I remembered that I mentioned this technique two years ago [7].
So there you go Smirk—a way that Edward Leedskalnin could have built Coral Castle (secret message to Spring [8]: maybe this is it, and maybe it's not).
