  abstract = {The problems of computer based painting are considered from a fine
              arts stand point. A detailed criticism of existing approaches is
              provided. This criticism centres on the limited depth of existing
              models and the resultant limited complexity and relative poverty
              of their mark making capabilities. The notion of the importance of
              the accidental in art is highlighted and an argument is made for
              its inclusion in computer based painting models. An informal task
              analysis is carried out and a description is provided for the task
              of domain modeling. The results of this task analysis confirm the
              inadequacy of the existing computer based models. A novel
              paradigm, Wet & Sticky, is proposed which models the physical and
              behavioural characteristics of paint rather than just its colour
              properties. The initial proposals for the model require that it
              mimics the actions of gravity and the effects of ageing of upon
              different types of paint. An experimental development procedure is
              used to produce and refine a set of algorithms for an
              implementation of the new model, resulting in an increase in the
              complexity of the proposed model. The final model includes
              algorithms which simulate the actions of surface tension and
              diffusion. Details are given of the behavioural parameters and
              algorithms required by the model. This new model is capable of
              supporting the production of marks which possess a greater degree
              of complexity than possible with existing models. Thoughout the
              development of the model the aim is to balance the requirements of
              producing a convincing visual and behavioural simulation of real
              paint, against the complexity of making a physically accurate
              simulation. The new model also provides the opportunity for new
              tools and techniques which are not only unsupportable with
              existing systems but also with traditional fine art painting
              methods. A selection of photographic results are included which
              provide support for the accuracy of the behaviour of the model.},
