Surely you can really only judge distance if you know the size of the object at which you are looking? Although anything is probably better than an almost-point source.

Depth (distance) perception is a lot more involved than just size comparison, with several cues/processes contributing to the bigger picture. I dare say that there are challenges to depth perception of a single point light source in the dark that a "banded" source would alleviate too. I suspect that our ability to process small and subtle changes/cues could be under-estimated too.
It sure is. Most analyses of perception now emphasise how the mind generates and tests hypotheses about the perceived world rather than using purely optical methods.

Probably most people have seen this. It's about perception. But if you haven't, watch it.

It's a versatile video because it can demonstrate either that you're so focused on the task that you fail to notice otherwise remarkable events, or that you're so easily distracted by background events that you fail to complete the task.

I haven't looked yet... but I'm guessing that a basketball is involved...

Yes, basketball themed.
The interesting thing is, the first time I saw it I didn't notice the other thing. Now, even if I'm doing what the video asks you to do, I do always notice the other thing. So there's something interesting going on there. I can't make myself "unsee".
