Would something like this be ok? (Sorry for the delay).

Oh, right! Almost forgot about this. This is my take on the this edition's Lenny. I liked Jyoti's idea of adding ears so I did that too, but I changed the overall color to white and added a tail. Still getting the hang of Inkscape. :p

Icon XML paste.

I've made the following icon, hope to hear some feedback. It's simple, black, tried to get the same thickness as the shutdown one. I'm not exactly sure what "add to rART" means, however.
