Good luck for the project! I might have been able to help graphics editing too,
since I edited most of the graphics in AAI2 project. It's a big project, so oneperson wouldn't need to take care of every picture.
And I hope you'll be able to turn this 90 degrees or atleast don't have two letters in one row,if turning is not possible.
I don't think there is a whole lot images that needs to be edited, but if we ever need any help we will let you all know! (As I did, when I stuck with the arc and tex files.)
I'm almost sure I can't rotate the buttons in the menu, but I already sorted out the multiple letter issue.
