I am not big fan of Scrum. Scrum is technique for lean manufacturing process - people each take 1 min tops to report what they've done and what they're about to do. Such a thing can hardly be used to boost morale or foster a jelled team.
What I might suggest is to have periodic meetings where a team member would prepare a lecture on a subject (normally related to work, but sometimes it can be something entirely different, e.g. if you spot that your team has developed an interest in some hobby, game, film, whatever outside of their working interests). A lecture could last like 30 mins and they people could engage in free discussion for another 30 min.
When our company was smaller we used to have these meetings and they were fun. One would either learn something, engage in an interesting conversation, etc.
