Particle systems make an excellent tool for creating tracks (which we call strokes) in vector fields. The question addressed in this paper is how such tracks should be made to vary in size and colour in order to reveal properties such as local direction and strength of the field. We find that for strokes that vary from large to small, direction is indicated by the large end. We also find that for strokes that vary in colour, the colour of the background is the most important determinant of perceived direction.

A language is described whose purpose is the investigation of meaningful motion using Stimulus Response animation techniques. The language is capable of adjusting the shape, size and velocity of an actor in real-time computer animation. Some results are presented showing how it is possible to generate such behaviours as chasing, avoidance and hitting using this animation technique. A set of primitives are presented which we find invaluable in the control of size, stretch and velocity parameters when attempting to produce fluid and meaningful interactions.
