This is Vincent, (all the little males are Vincent and females Vienna, I can't actually tell each one apart!) I've cornered him near a log to try to get some nice photos, he is much smaller than Vienna, and curious too.

Update: This is NOT Vincent, because he is not the spider I thought he was, thanks to Evan for the correct ID, this is Syrus the Sitticus pubescens, now maybe he will come when I call...
