this blows my mind. the "invisible car" would only work if you view it from one particular vantage point. if you're a little closer or farther away or if you're standing off to the left or right, the perspective painted on the car wouldn't match the surroundings anymore.
what's amazing is how she kept the perspective internally consistent. that is, when she painted the back of the car with perspective suited for a particular point of observation, how did she manage to paint the hood of the car with the exact same vantage point? if that point moved even just a little bit as she painted different car parts, there wouldn't be a single spot where all of the car would merge with the surroundings this well. when she was standing next to the car to paint, how did she keep it consistent?
