Playstation and IE logos?

First, when you just start the game, you're asked to kill every monster in a cave. When you come to this cave, you see some blue painting on it... look it well, doesn't it look like Microsoft Internet Explorer's logo? :)
Then, in the second act, when you are in a kind of sanctuary flying in space. There are large square platforms with four icons in the corners and if you look well, you might think these are Playstation buttons :) (cross, triangle, round, square)
If you find this kind of crazy logos, just post'em here.
