  • Actually, there's typically a 1 frame lag on the TV. When you put stuff in front of the screen, the dealy between the frames becomes evident. The psychadelic effects come from the lag on screen, then the camera posting it as the next frame comes along, and continues.

  • @georgef551 Ok, that makes sense that there'd be some delay, but image-lag alone should just result in a delayed image (with each frame down the infinite hall being further back in time, which does happen).

    Where do the patterns come from, and why can you always get the same style of pattern? Why is it blue? I think looking into the reason that the pattern is blue will take you down the path most likely to get the answers. I should test to see what this looks like on an LCD screen.

    It's based on the last frame that had an image on screen. As it mulitplies, it looses information, and distorts. Any natural shaking, or tilt, will produce twisting/spiral effects. If you can keep the camera perfectly still, the effect will come, ang go, and stay black. It's very hard to do, sine somthing usually winds up on the screen.

    Of course, allignment and linearity on screen helps with effects, or kills them.

  • @georgef551

    I see. So each frame is a slightly distorted version of the previous one, and this continues until nothing is left of the original image but the amplified distortions.

    In further experimentation I've done with this, I found that the closer I line up the camera to be in-line with the screen (staring straight on at the center of the screen) the more ordered and regular the pattern. I think that if perfectly aligned, the pattern displayed would be just parallel stripes.

  • @HansLemurson

    I believe it might just simply go black. I've done it only once, and never repeated it again.

    When you get closer, the fish-eye in the video adds disortion. I think it just goes to a ball at this point, and no idea if the image was pincushioned. It's all weird. Can't explain much more.

  • Pretty sweet.

  • Woohoo! My first video on youtube!
