Turing Complete Hearts

You may have already realized that our minds are Turing-Complete, in the sense that given a pen and paper tape we can simulate a Turing Machine.

However, Turing-Completeness also emerges in nature else-where.

Implications of the Turing completeness of reaction-diffusion models, informed by GPGPU simulations on an XBox 360: Cardiac arrhythmias, re-entry and the Halting problem

Also, this gives me an idea,
An OS made of FPGA elements working as network of apps, without central controlling kernel or thread(communicated as dataflow among circuits, similar to objects in The Conway's Game of Life).
