practical the use of proof during design.' The style of presenting the data abstraction is via a model. Again, Hoare expresses 'amazement at the attention (the property-oriented approach) is still receiving utility for basic data types he comments that 'the complexities of application seem to require the model-based approach, which takes for granted the basic prop- erties of data and structures.' The idea Reserved. 134 About the artist Dan Zucco London-based 3D art and motion director Dan Zucco creates repeating 2D patterns and brings them to life as 3D animated loops. Inspired by architecture, music, modern
