it's like a nature documentary in my bathroom

For quite some time there has been a big spider living in my bathroom (not tropical spider big, but really big for these parts). Since there are no dangerous ones here, I have nothing against spiders (as long as they don't drop onto me) so I left it in peace. And just now I looked at its web (it's visible from my toilet, so I can't help but notice the developments), and I think it must have reproduced, because there are now something like two dozen tiny things in the web, which has a different shape than usual too, like with a ball structure in the middle rather than just a few strands (it never made a really nice regular web, just some threads). And while I can't get quite close enough without a ladder to be a hundred percent certain, I'm fairly sure the tiny things look like lots of little spiders. So now there is a developing nest of them or something. I don't think I've ever actually seen (or rather noticed) baby spiders outside of nature documentaries before.
