ARTetriCAN is a free-and-open-source augmented-reality Tetris variant for Android devices. You print out a target label, wrap it around a can or bottle, and use your Android device to play an augmented-reality game cylindrical Tetris-like game.
The target label is a color PDF file. I don't own a color printer.
Does ARTetriCAN work fine even if the target is printed in grayscale?
