One Pixel Live, Projectior, Camcorder, Computor, 2011
관객의 모습을 실시간으로 촬영하여 화면 중심의 Pixe 하나만을 전체화면으로 프로젝션하는 작품
이미지는 없어지며 색상의 변화만을 보게 된다.

/*
BLEND - linear interpolation of colours: C = A*factor + B
ADD - additive blending with white clip: C = min(A*factor + B, 255)
SUBTRACT - subtractive blending with black clip: C = max(B - A*factor, 0)
DARKEST - only the darkest colour succeeds: C = min(A*factor, B)
LIGHTEST - only the lightest colour succeeds: C = max(A*factor, B)
DIFFERENCE - subtract colors from underlying image.
EXCLUSION - similar to DIFFERENCE, but less extreme.
MULTIPLY - Multiply the colors, result will always be darker.
SCREEN - Opposite multiply, uses inverse values of the colors.
OVERLAY - A mix of MULTIPLY and SCREEN. Multiplies dark values, and screens light values.
HARD_LIGHT - SCREEN when greater than 50% gray, MULTIPLY when lower.
SOFT_LIGHT - Mix of DARKEST and LIGHTEST. Works like OVERLAY, but not as harsh.
DODGE - Lightens light tones and increases contrast, ignores darks. Called "Color Dodge" in Illustrator and Photoshop.
BURN - Darker areas are applied, increasing contrast, ignores lights. Called "Color Burn" in Illustrator and Photoshop.
