Can't see it in motion, but I'm guessing the second one is a failed script / algorithm for a flock of birds? It'd tell the birds to flock together, but not too close, and follow this path but not exactly, and with some variation.
I've seen a few gifs where the birds just clump up tightly to the point of looking like a flying bush until it gets closer.
The guy takin a piss there? I got nothing lol
Reminds of one time I was at Sears and had to piss so bad... sorry about that carpet in the changing room, I really am. It was either me or that carpet so yeah.
Edit: You could use imgur.com.... at the top there's a drop down to convert video into gifs. Then just link. Good for very short stuff. There's also gify.com
