I ordered one of these, 553pb017b , R2-D2 heads from bricklink, and when I received it I realized the head orientation was printed at an angle, making it look like he is looking around. At first I was kind of upset about it, but then when I started looking online and didn't see anything else like this, I realized it was actually pretty cool, as every other lego astromech droid is infinitely stuck looking straight forward.
