King Kong Easter Egg - Someone's Initials

When you first start the level "Kong's lair" you begin in a dark cavern. Follow this to the end and grab the rifle from the box. Go up the first steps and take out the bat at the top of the steps but instead of walking up the second set of steps, walk directly to the cliff edge to the left of the second steps. Take out your sniper rifle you picked up and look over the edge. Way out in the bushes you will see a strange open area. In that area you will see the letters C and D. I couldn't figure out if this was one of the creator's initials or what. But hey,it might as well be Carl Denhim.
