This fundamental data structure represents a field over a (discrete) piece of space-time. It is used in the simulation of dynamical systems. A fabric unify the concept of stream and collection and can be viewed either as a ``stream of collections'' or as a ``collection of streams''. The name come from the title of a Fellini movie. The main features of the 8 1/2 programming language are: Line 12 ⟶ 13: * 8 1/2 programmes are hierachized through the concept of system. * The 8 1/2 language is naturally a data flow, data parallel language. * A static 8 1/2 programme (i.e. a programme involving only fabric with static shape) is detected by the interpreter and can be compiled (in sequential C or towards a [https://en.WikipediA.org/wiki/SIMD <abbr title="Single Instruction, Multiple Data">SIMD</abbr>] abstract machine).
