Hi speed T-shirt removal

Hmm, interesting. I don't go to Reddit at all, so I don't really know what's there.

The reason I find this interesting is the topological analysis behind how this works, but other similar tricks (such as a shirt) don't. It's similar in nature to the way you can remove a vest (waistcoat to the British) without removing your jacket (or coat). The vest was never really "inside" the jacket at all.

So can this technique be used to remove a pullover? In theory if your first grab is at the opposite arm's elbow then you can retract that arm, but then it's difficult to get the power and travel to get the pullover over the shoulder.

This is then related to some of my programming work where I'm trying to find paths for robotic arms through a weird topological space. It's got about 11 dimensions, and it has "holes" because there are positions the arm won't go through.

These are the things I think about when I see this kind of trick. I guess you don't. Your reply makes me realise that I need to explain more when I make this sort of submission. To that end your comment has value to me. Thank you.
