We had project-wide design review meetings on Monday and Tuesday. Everyone that made a ‘worthy’ contribution to the discussion got a star from the project manager (and so lots of team members got a star, and the one in the picture is mine). The star is a stellated heptahedron of sorts. A heptahedron is a polyhedron with seven faces and the ‘stellated’ means that pointy pyramids were added to the faces of the polyhedron.
