ViZ makes mechanical special-effects, often using models made by us, for advertising, photography and film. Our models have been used by musea and trade-fairs. Physical-models can appear to be completely “realistic” when used, (with discretion), in film or photography. We use these kinds of models for our “product special-effects” for advertising. An example would be food-models. Occasionally we will be asked to illustrate or design characters using the model-making technique.
