So, this video is straight-up awesome, as is the song, which was the inspiration for the video. Over at Boing Boing, they have an interview with songstress Kim Boekbinder, artist Molly Crabapple, and animator Jim Batt, who collaborated to put this thing together. The interview also features behind-the-scenes photos, which give a sense of the scale of the project. The figures look to be maybe six inches tall, while the paper-craft buildings are maybe three-feet tall.
If they're smart, they'll auction off the set, for which someone would certainly pay 10 kajillion dollars.
Speaking as a biologist, I should note for the record that I am unaware of any replicated, double-blind studies showing a statistically significant association between organ transplants and having steamy lesbian pirate sex with cats.
Update: I just went and checked out the dedicated website (ihaveyourheart.com), which has a series of blog entries following the project from its beginnings in May 2010 to July 2012. Awesome.
