From the Sword's Perspective

[Vekseid]

Spin Around

Kindof weird.

Wow... It's a good thing swords can't get dizzy and sick...

Super cool vid, though!

[Spell]

 Now I wanna see a swordfight with the camera attached to it!

What I find fascinating is that, though I know the swordsman is moving the sword, it is all but impossible to view it without the impression that the sword is moving the swordsman, who is merely dangling from it.  The disparity between what I know and what I perceive watching this is quite disconcerting and also interesting me as to why that happens.

It's probably the fact that the camera registers as 'stable', because that's what cameras are supposed to be.

This.

People have the perception that the eye is like a camera, passively recording what it sees, projecting it onto the retina for immediate viewing.  But the reality is that the brain is intimately involved in processing that data and rendering its version of it, which is what we "see."  This is how optical illusions work: exploiting known weaknesses and foibles in how the brain processes visual information.

I actually had the opposite - a sense of vertigo while I was watching, like "Why aren't I feeling directional changes and acceleration?"

You could probably figure out how quickly the tip of the sword is spinning if you figured out the speed of revolution and the length of the sword and the arm. Given that when you hold a sword out at full extension and spin, it has to complete a wider circle than your shoulder in the same amount of time, the sword tip will be covering more ground in the same amount of time. So technically, even though it has the same speed as your shoulder, it is moving faster. Or, moving differently. I'm not sure. That's about the extent of my physics.
