Love that movie . perfect length ! <| sep |> When you have to say , those 303 , 563 people are wrong and I am right , one only has a 1 in 303 , 563 chance of being correct . <| sep |> Seems like a dropping funnel to me <| sep |> This one seems natural , I mean , like the walls are actually that color look how her shadows project over the walls . What intrigued me was that there are other videos by the same channel with the same physical structure but with different colors . So , maybe is some kind of transparent material that they can change the color at will like the towers in Los Angeles international airport . ? Anyways , I did something similar some time ago , without the 3 d effect , and I was able to show quite a rainbow . look here contentuploads 201309 slider . jpgIt ' s not complicated Just place the subject far away from the background a white wall and place a few 200 w lights with colored gels , and shape them with the barndoors or flags . I didn ' t use flags on this one , and that ' s why there is no definite border between colors , although that is what the director wanted . I wanted to recreate a rainbow flag .
