I really like code that speaks for itself, like this example !
Great, Laurent.

It can even be written shorter, like this:

| md5 url |
md5 := MD5 hashMessage: 'gsa@arsol.net'.
url := ('http://www.gravatar.com/avatar/', md5 hex) asUrl.
(ImageMorph fromStream: url retrieveContents contentStream) openInWorld.

I was looking for such brevity, cool !
