wolfram answers over an animated parade of terry gilliam-esque cut outs of paintings by botticelli , el greco , titian , of annunciations , births , madonnas and child : the angels dont just hug the humans in the foreground of botticellis bucolic mystical nativity , they clasp desperately to their human brethren to keep from lifting away , their white rumps rising indecorously above their beating wings ; the manger animals emit green drifting gasses disturbing all but the ethereally enamored madonna ; while the heavenly hosts above the nativity get carried away in their own loony joy as they start swinging and rocking gleefully , trying to spin the dome of heaven theyre dangling from until they break free and whirl away like tassels on a lampshade .
