Is Google's Rorschach Webtoy today genuinely making random images?

Today Google celebrated Rorschach’s birthday by making a webtoy that generates inkblots. Just go to Google today only to see it.
The idea of inkblots of course is it’s just a random picture, but you can discern the mind of the thinker by seeing what he pictures in it.
Some of the pictures seem genuinely random blots. But I clearly saw a pair of garden gnomes, a pair of dinosaurs, and a butterfly over a cat.
Is the ink blot working? Am I reading too much into random blots? Or is the webtoy seeding actual images into it?
