What is it?

What is this creature? I've seen them living on the walls of all the houses I have lived in here.

It's the cocoon of a case bearer moth, I believe. I first encountered them stuck to the walls in my house in Micronesia; I had no clue what they were at first.

Some images here. The scientific name is "Tinea pellionella."
