Rainbows are made from panda vomit

Not sure what Flickr has up its sleeve, but here's a nifty Easter Egg. If you happen to explore the panda category, you'll be greeted with a (happy?) panda with rainbow vomit and photographs spewing out of its mouth.

It's just so bizzare and awesome at the same time, you'll need to view it for yourself.
