Ah, I see now. You can try to reverse-engineer the existing mechanism for the “gallery”-format project items, adding a capability to display text instead of images (see the “content-gallery.php” and the “/scripts/orbit” theme folder as a starter). Alternatively, you can try creating your own jQuery code that would rotate several div elements inside a single project box. Finally, the “quick and dirty” way would be to simply convert quotes into images and add them into “gallery”-format posts ;)
I hope this helps at least a bit!
