Twenty-two people convened over the day in Toronto (Figure 1) , including ten presenters. The traffic count during the day indicated 500 avatar arrivals in Second Life ® , four of whom were presenters. The workshop was advertised to pertinent groups in Second Life ® and open to the avatar public. The Second Life ® building includes a location where the original slide presentations can be viewed ( Figure 2 ). Two screens were used in Toronto, showing the slides and the audience (represented by avatars), while Second Life ® participants could lecture by having their avatar stand near a virtual screen in Second Life ® . Everyone could hear everyone else. A second virtual screen showed a live camera view of the audience in Toronto (Figure 3) . The all-day meeting had only a few short interruptions for technical reasons. A summary and follow-up discussion was presented at the annual meeting of the Society for Mathematical Biology shortly afterwards.
