Visage, an LED Mystical Hood costume
The costume is a fork of Adafruit's Mystical LED Halloween Hood. In addition to the two LED eyes from Adafruit's tutorial, Visage adds one more LED, forming a triangle, or an alien face, or a Kodama face (Ghibli), or a "because" sign, or trisight, or a "therefore" sign.
