It's very beautiful.
To film the GID. You have to take a long exposure. You have to have the camera on a tripod, no flash and leave the shudder open for like 20 seconds so it absorbs all the light. Also helps to "charge" the quilt right before you hit the take picture button. I used a black light.
That's how I filmed the ones I did. And this is how they actually look in the dark.
