It'd be great to see the iSight script if you're up for sharing. I also wonder what was wrong with your MBP, from the photos it looked like there was some initial activity and then a lot of nothing, then a final check and I guess they returned it fixed? Hilarious, thanks for sharing.
It depends on a library called CocoaSequenceGrabber. I'm sure you can find it somewhere, but the first Google link seems to be dead. I also have no idea whether it works on recent versions of OS X.
A fan was making a lot of noise. (Not just the usual noise fans make when they spin up; it sounded broken, like it was grinding against something.) They couldn't hear it, and didn't fix it. (Later, I brought it back and asked them to please just replace the fan, regardless of whether they could hear it. They did.)
