On computer geekery and music

So, yeah. On my Facebook friends, someone, who'd shared only with friends, otherwise I'd link to it and give her name, posted that she'd woken up this morning from a dream in which she was writing a sort algorithm, which finished with a dance number/music video.

And she woke up singing, "Every datum shuffling, shuffling. . . "

For those who don't get it -- and especially for those who do -- check out this music video of "Party Rock Anthem":

Anyway, the thing is -- in the comments to her Facebook post, someone pointed out that you actually CAN watch a dance number with every datum shuffling, to various folk dances:
