I give up for now, until I get any more ideas. I actually went through all the CSS that I could find (found references to poal.css, but couldn't actually access it.) and front page markup. One thing's for certain: they did a good job hiding anything that would render a bunny. There's some SVG fuckery going on, and didn't care enough to test all of it out, but one of those might just be the bunny we're looking for. Nothing really stood out, though.
