This reminds me of one I saw a few days ago. A huntsman dangling from a stick a few inches off the ground. I was working on the plumbing in my usual fashion, forgetting things and going back in the house repeatedly for some part or tool. So I'd glance at the spider in passing. At one moment it was vibrating. Another is was doing track and field warm up exercises. Then poof, two spiders. All in the span of around half hour. My point of view was like a sped up video with most of the frames removed, the spider explaining as time went on, 'It's easy, I do this, this, this and there we go!' and after a few minutes rest it casually strolled away.
