These sketches explore how an individual might evolve over time and explore the ability to play with borders of a shape. One of the goals was to depict a continuum between two extremes, for example active participant - lurker, friendly - unfriendly participant who may flame frequently, etc.
We realised that although we can designate the concept of smoothe to spiky as different characteristics, these shapes still failed to convey the different personalities. This was because the shape's outer edge was too carefully crafted and controlled.
Another important aspect was the challenge to design a system of shapes using colour and form that could map across an entire newsgroup and intuitively show different levels of abstractions (i.e. visual reading that the shapes are mapping different participants as well as showing different characteristics of each participant such as activity, amount of flaming, etc.)
