I might be wrong on this one, but my best guess is that this is some kind of Running Crab Spider, perhaps from Family Philodromidae.

It was very tiny, the body being only a couple of mm long.

I'll update this later if I find a better ID.
I don't think I've come across many spiders like this here, or I've just never noticed them.

I thought it was some kind of jumper at first, but once I got it blown up and looked at the eyes, I knew that couldn't be.
