I looked up the beast. This is apparently a "cellar spider", family Pholcidae, perhaps genus Pholcus. They are also called "daddy-long-legs spiders", not to be confused with Harvestmen which are also called "daddy-long-legs" but are not spiders.
The eyes of these spiders are organized as two groups of three (one group on each side of the carapace), plus a smaller median pair, black in this picture. Judging from these shots, the inner eye of each group of three seems to be strongly retroreflective -- perhaps a different angle would show that all the eyes have the same feature.
Their webs are not adhesive, but instead have a very fine irregular structure that mechanically traps prey. I could not even see the web, but when I tried to reach the spider by probing at it, clearly there was web at least a half-inch around the beast.
Wikipedia has a good article about these spiders.

PS. Ken, there was another one of these beasts inside the house, over the sofa. But it was much bigger -- must have been at least 3" legspan!
Canon 300D, Sigma 105mm macro at f/11 and f/7.1, electronic flash. Body width approximately 1.2 mm, leg span 35mm.
They are more of an annoyance than anything else. I think Wim, I'm not sure, made a post saying that they eat other spiders, which is good. 
Very nice photos
