This is something I noticed long ago. The tiles in our bathroom at the office have a very rough texture and I see faces in them. This happens to me often, I make a face out of some random texture. But these faces seemed pretty prominent and I wondered if I was crazy to see them everytime I venture to the loo. So here they are for you viewing enjoyment. Look at the posts below.
(Incidentally, if you don’t see what I see click on the photos and go view the notes I have placed over them in my Flickr.)
