A two-layer wind-guiding shroud includes a base. The multipart data file includes an interactive virtual instrument object and a global accompaniment object. The first and the second gradient index lenses have such refractive powers that both the fast and the slow axis of the astigmatic laser beam are converged to a focus inside the third gradient index lens. Each team member monitors for a transmission event and responds to a transmission event by generating a re-planning operation, whereby each team member will produce a coordinated replan for itself and each other team member, whereby the team members remain coordinated.
