You know that point in math where you think you understand the problem and the next step comes, then you return to being completely lost? Yep that's me right now. While I'm following that little balloon in the sky, I'm probably not going to completely follow until it hits the LZ. I'm hoping you'll be doing an in depth explanation when you've got it completely figured out. Maybe then that dim little light above my head will turn on. Looks awesome regardless, keep it up!
