Ran across the video of Björk's All is full of love, which I'd never seen before. Wonderful visuals, and the behind the scenes video explained why I couldn't tell if it was done with CG, greenscreen or practical robots.
Then I made the mistake of clicking "View all 3295 comments". Jeez. I guess if I ever want to get lots of angry, poorly spelled, barely comprehensible comments on something, I should include a pair of female androids kissing. It's amazing how many people feel threatened by that.
