mine was green, not like granny smith, but more like a green pear; rugged and not shiny. No leaf(s) either. Realisticly depicted. But my though briefly envisioned the white apple logo... just for a second, before settling for something better.
tasks like face recognation
At work I usually keep typing and watching the screen when people talk to me, which sounds rude, but I'm just running a thought process I do not want to interrupt and spawn a new process to talk to a person. This is only for short chitchat, for things that I need more brainpower I stop my work activity and face the person. But now that you mention that it takes CPU cycles to read a face, yeah that feels exactly why I avoid the face. But just being behind a computer takes cycles away, even if I am not doing anything. So to think about an algorithm, I need to move away, walk, bike, or have pen and paper... that allows for more CPU cycles for thought.
As for the imperfect rendering, I have something similar to gauge distance, because I have one lazy eye I can not rely on depth (no natural eye focus), so I need to 'calculate' it. And I map wireframes over the landscape to do that. On the plus side is that this wireframe, when in a building, has all the exit points, which makes me feel save. Drawback is that I want to know what's behind closed doors, or I have to ignore that part in my head (like in a 3D game with halls that are blocked).
A friend has colour blindness and he also has this mental struggle to identify the colour based on best-guess. So if the brown looks like something he knows is red, then his guess is red. He does get it right more often than not, so his heuristic method works.
The supermarket near my house remodeled. And everything is in different places. I am still learning where everything is, but it is hard, because I overlap the old layout in my mind. I went to a new supermarket 3 times, and I remember where things are... but not my nearest supermarket. Strange, that.
