Before we begin… I know, there’s nothing particularly special about drawing on a screen in 2D and making objects move. However, the device I’m using isn’t actually designed to do this.
The ODroid GO is a handheld console that sells itself as a device that will run emulators of all your favourite 8bit systems. And it does that job rather well, I spent at least five minutes with mine playing Tetris, and it was a good emulation.
Big systems are interesting; they’re complex, have many interlocking and interdependent parts and exhibit really fascinating emergent behaviour. Take a hospital, for example. You go in the door marked “EMERGENCY” and talk to the person behind the desk, while wondering just how bad the top of your head is.
