Starcraft (Brood War) on Android with full touch controls.
Great, now that I have your undivided attention, let me explain. So, you, like most reasonable human beings, think playing Starcraft on a tablet would be pretty awesome. It's been tried before, but usually the result is a messy, laggy ROM on an N64 emulator that requires you to control a cursor with a digital joystick. And as we all know, that's basically like poking yourself in the eye with a hot fork. It sucks.
Enter Winulator. Right now, Winulator is still a pretty young app with a lot of potential, but what it does is really quite fascinating.
