I love to photography. So Interestingly a few people have had that response. I tried to soften it and make it look more organic by making each ray fade in a tiny bit, but it still looks artificial, you're right. I actually wanted the effect to be less noticeable, as in a seamlessly flowing cascade of spectrum-dictated colours.
Thanks, it's very different than the other videos that are being submitted, so we'll see what the voters, and what Sigur Ros thinks (there is a community choice award and a few that Sigur Ros chooses.)
