I'm not a big fan of the Software Center icon (apparently I'm not the only one: http://www.omgubuntu.co.uk/2011/09/software-centre-icon-proposal).
Is there a way change it?
The answers to this related question doesn't make it clear whether there is: How to change the Dash Button in Unity Launcher?
As far as I can see the Software Center icon isn't in
nautilus /usr/share/unity/5/ so where could it be?
