A realistic model, even only of the external shape, of an organ of a living being is very hard to be implemented since we do not know – or perhaps it does not exist - a program code (algorithmic information) *shorter* than the list of the co-ordinates of each cell (roughly represented as a point on a screen). It may be that the biological code (DNA and more) of a true organ is *irreducible to a shorter string* than the list of all the co-ordinates involved (*incompressible string*).

Only a very poor representations can be obtained starting from a short string lika that of a computer program based, e.g., on the parametric equations of a manifold in 3D space lke the following ones.

**Realistic heart shape generated sequentially by smooth triangles (uncompressed list of data: long string)**

A realistic model based on anotomic images has been realized by Bob Huges (open source:http://objects.povworld.org/cgi-bin/search.cgi?X=heart) based on a decomposition of the heart shape into *smooth trinagles.*

Acting on the uncompressed list of the co-ordinates of the vertices of triangles one is able to obtain a sequentially ordered plot of the heart shape.
