CCK checkboxes columns

Hello. I have a CCK content type with several fields that are long checkbox lists of taxonomy terms. I would like to be able to render the checkboxes in columns so that filling out the node form will not require so much scrolling (and to just make it look a little nicer). I'll attach a screengrab of what I'm after. I've been searching around for a couple of days but haven't found a good way of doing this. Any ideas on how to accomplish this much appreciated.
