Try and add text that gives the author's name when your mouse moves over the author's ship. Alternatively you could have the author name displayed at all times. Or include a legend so that we can differentiate between the ships for each author.
Also try and have names for the packages and classes as well when the mouse goes over the object.
Note: Only do this if you have time and if it isn't too hard to incorporate into what you already have
