Recently we started using avatars on our Kanban board. We are certainly not the first to do this, however I was surprised by how excited and rejuvenated the team became. If you have never tried this I recommend you suggest it to your team and see if they go for it.
Not only is it fun, but it is also practical. With one look at our board we can see exactly who is working on what and who they are working with. Each person has one avatar on the board, therefore they can only work on one task at a time. Occasionally someone will start work without updating the board, but this is very seldom.
We went for the classic South Park characters, each team member got to draw themselves, here is the result:
You may have noticed that my character (Daryn) is a bit stressed out. This is a reminder to myself, that as the ScrumMaster I should not get overly concerned about everything. I need to trust in the team and leave them alone to get the job done. I need to remember that a ScrumMaster is a facilitator and not a manager. For me, not acting like a manager is the most difficult part about being a ScrumMaster.
