Queues and Shows of Hands

One possibility for showing who wishes to speak, and with what urgency, is to place an icon for each user (either a small photograph or name tag) on the screen some distance from the ``floor'' window. As the time approaches for them to speak, the icon moves closer to the floor. One possible implementation of this (due to Taylor) was a step functioned ``fish-eye'' lens model of the area around the floor, with icons nearer the center naturally being larger.
