I had a 10-page term paper due one day. I wrote the entire thing IN the class that it was due in, the DAY it was due. While the other kids were presenting them, I elected to go last, spent the whole period frantically typing it on my laptop under my desk, slyly passed the laptop across the room and had my friend print it. Luckily the teacher is nearly deaf.
Lamp - No. I just happened to have mine with me for a video project, so I sort of held it at a weird angle, almost closed, behind the desk, and typed as quietly as possible.
I was pleased. I finished, (oh, and I had to hack into the neighbor's wi-fi, because I kinda hadn't done any of my research yet.......) and I had NO typos. Even though I wasn't watching the screen for most of it.
