One way is to make Pixmaps that represent text strings (and put them
on a fine raster).   Another way is to put the agents on a Canvas, like this:

#import <simtools.h>
#import <gui.h>

#define WAIT while (GUI_EVENT_ASYNC ()) {} sleep (1);

int
main (int argc, const char **argv)
{
  id <Canvas> canvas;
  id <NodeItem> critter1, critter2;

  initSwarm (argc, argv);

  canvas = [Canvas create: globalZone];
  [canvas setWidth: 250 Height: 250];
  [canvas setWindowTitle: "Canvas"];
  [canvas pack];

  critter1 = [OvalNodeItem createBegin: globalZone];
  [critter1 setCanvas: canvas];
  [critter1 setX: 100 Y: 100];
  [critter1 setString: "Critter1"];
  critter1 = [critter1 createEnd];

  critter2 = [OvalNodeItem createBegin: globalZone];
  [critter2 setCanvas: canvas];
  [critter2 setX: 150 Y: 150];
  [critter2 setString: "Critter2"];
  critter2 = [critter2 createEnd];

  WAIT;

  [critter1 moveX: 50 Y: 0];
  WAIT;

  [critter2 moveX: 0 Y: 50];
  WAIT;

  while (1) { while (GUI_EVENT_ASYNC ()) {} }
}
