Mass of spiders!

Found this in Alentejo, Portugal. Interesting behavior.

I was taking a walk (this was in the Summer) when I encountered a strange spot underneath an old pig feeding trough. When I moved closer I realized it was a bunch of spiders who had grouped themselves into this. The next day I returned to the same place and there they were. Anyone care to explain this interesting phenomenon? Why do they do that?

PS: Sorry for shoddy camera work, I had a Sony Handicam with better footage, but to put those videos in Youtube is too much hard work :D
PPS: What's said in the video is: "How can I disturb them? Don't you have a rock?", my father then replies "They have been disturbed now" and in 0:40 I say "Gross".
UPDATE: Recommend reading this article http://en.wikipedia.org/wiki/Opiliones#Behavior
especially that last paragraph.

When I was hallucinating on some amazing drugs, I saw one of these on my wall but fortunately for me they weren't this scary.

They're not actually spiders, they're havestman, but yeah it's still pretty gross, no matter what they are, lol.
