Heh ... you're right on. I've left some traces here and there of the new elements' names but if you divined them through the icons, that's impressive, especially considering you can't see the large sizes.
Uh, you do know that you included the name of the elements in the URL they're hosted at right?
A simple mouseover or click displays the URL, from which one can extract the names.
If you want to keep things like that a secret, use a different name for them when uploading. <(-_-')>
