The Complexity of GTA V

I've been playing Grand Theft Auto 5 for about 80 hours now. I've beaten the game on story mode. But when I first started playing, was was absolutely blown away by the graphics and the amount of just pure stuff that was in the game. People talk to each other and interact on the streets, buildings are more than just storefronts, the island is a gradient from wealthy to poor, etc. But it got me thinking, how do certain things in this game actually behave? Is it random? Or is there some basic AI behind it? I decided to find out.

Repurposing a Printer's Parts

I'm sure there are a billion things out on the web that show how to repurpose a printer. But I'm doing this for the purpose of making that damned CNC machine that the CD Drives just weren't good enough to do. I bought four of them and, wouldn't you know it, only two of them had stepper motors in them. That's okay though, because I still got the other two motors out (a brushless, and a DC) and kept the other laser movement motors just in case. I said I'd be taking the laser apart, and I have, and I'll post that next time. But let's just say that I didn't get any of them to light up like I had planned to. In fact, one of the chips on the laser box kinda blew up. So yeah, the whole laser thing is bust. But hey, we got this neat printer to take apart!
