While visiting the sculptures yesterday I spotted a cobweb across the face of one of the sculptures. As you can see the spider had cleverly placed this bug into the eye socket. I find masks creepy at the best of times. The legs look like eyelashes.
As I was looking at this pair of photos, I was thinking something similar to what I then read in your comments. I think the one on the right is eerie, but the one on the left is pretty cool. I like the legs as lashes and the webs above looks like hair in its eyes.
