Recently started looking into the whole ambient light/phillips hue type of thing. Not sure if it's something I'd want to proceed with or not. How much of the image/video is used to light up the lights?

And, those strips, are they bendable? If I did anything with them I'd most likely want it used for my projector, and right now my screen rolls up/down.

Using Ambibox, you can set the capture area as big or small as you want for each individual LED.

The strips are bendable in the perpendicular directions to the plane of the strip but cannot be 'rolled up' as tightly as a projector screen, so it is unlikely that you could mount them to the back of the screen and have them roll up and down with it.
