From the developer:
Blink/zone is a demonstration of NeuroSky's blink detection. Blink to set off a firework. The bigger the blink, the bigger the firework. You can try to set off many at once or try a game of maintaining your calm. The color and height of the fireworks are based on involuntary brainwave activity.
You may want to check out more Mac applications, such as Jets'n'Guns, Kivi's Underworld or Mars Explorer, which might be similar to blink/zone.
