There's a solution which is both open source and would interact with Trac tickets. It's called JimFlow and can be found here:
Some benefits of it for you are.
- Print tickets directly out of the ticket system
- Supports flow boards with columns
- Take photos in custom intervals
- Generate digital version of the board with ticket title and type
- Update ticket in ticket system on movement
Overall, it will allow you manage your Trac Kanban board virtually and your physical real world board simultaneously.
