Hey Chris,
quotes in Ikebana are constructed as simple text in a box; if you need them appearing in an overlay on mouse click, you would need to alter the “content-quote.php” template file to have the items act as links, and then use a plugin, e,g, this one, to display these is an overlay.
You can also try using one of the Thickbox plugins for displaying videos in overlays, but you will also probably need to change the link on these items from pointing to the underlying project item to pointing directly to the video.
Sincerely,
Andrew / Satori Studio
