You did ask for most complex, didn't you? Bryce looks hard, and it can be; but there are many people out there working to create come really cool things in it. Instead of disbelief, take it as a challenge. That's what I do. I can tell you right now, some of this stuff looks just insane, and most of it is. But when you start getting into it, and you see how it works, it gets under your skin, and you have to finish no matter how many little balls it'll take. If there's on piece of advice I can offer it's this: Don't forget about the Lattice tools. You can get all kinds of crazy organic (and inorganic) shapes with that thing that you could never make with balls and boxes. Best of luck with it!
