I have added a new glossary format to contributed modules and plugins, called "flashcard style". It combines the flash card and glossary together as a tool to memorise terminologies. Users can click on the link, it will flip the card and show them the description of that concept.
Note: It's still haven't been approved in moodle.org, you may download this new glossary format from my blog for the time being. Feedbacks are welcomed.
