Well if you take a look at the focus eye on top of the LED eye, to the right, you can see those 3 wires (yellow, red, black), which is connected to a sensor and if you wave your hand close to it, the LED eye blinks and makes other images.
My head was too big to cover my right eye to make it look like I'm a cyborg. I wanted to wear it at the art gallery where they were showing MFA work, but I had to leave.
