This isn't something thats extremely difficult to do. You will need to create NSView subclasses for the scores at the top. You can use NSAttributedString/NSMutableAttributedString to create styled text, and use their drawInRect method to draw the text into the view. It would be a good idea to read this:

And more specifically, this: https://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/CocoaDrawingGuide/Text/Text.html#//apple_ref/doc/uid/TP40003290-CH209-BCIEEIGC
For the scrolling scores below, you will have to put the scores into an NSTableView, or an NSCollectionView (the latter is better if you want to customize the display) inside an NSScrollView. As for the automatic scrolling, NSScrollView has nothing built in to facilitate this. Most likely you are going to have to use an NSTimer that fires every few milliseconds, and uses NSScrollView's scrollToPoint: method to scroll gradually until you hit the bottom.

I will pull the scores from a CSV file (which is updated regularly) and sort them into arrays for display. Creating the on screen graphics is something I have not done much of with Cocoa. The organizers have asked for a full screen display and would like have the top 5 scores at the top of the screen and then scroll the rest of the field below these scores.
