Just an idea, but maybe I can be a bit more imaginative that simply displaying a direct quotation as a text. Maybe I could take a cut out of the screen shot and paste it in as an image? Or maybe I could do something like this:
If I do go with this idea, I could similarly use it for indented direct citations within the literature or citing course documentation. Actually, that could be a bit like overkill and would reduce the sense of voice projected by these quotes. Maybe it works better when it has been someone's spoken words.
I wasn't sure about this when I started typing, however I quite like it now as it does bring key bits of data - and they have to be key in order to be reproduced directly - to the fore. Also, there are some really fantastic lines in the data that merit being foregrounded like this.
The font if Clarendon BT, the same as for the title on the front cover. Does it appear more book-ish than conversation? It's a nice clear font though. Maybe this would work for quotations for text as well, but perhaps without sing versus double punctuation marks.
I like this.
