Here is a core concept of Tau which needs graphic designers to create an info graphic. Automatic programming (program synthesis): https://steemit.com/tauchain/@dana-edwards/tauchain-the-automated-programmer

The infographic should show the human beings of all shapes, races, ages, communicating in various languages, which then is translated into "machine language", which becomes a "formal specification" for the automatic programmer to go to work. The automatic programmer is really just the AI built from the "expert system" or knowledge based approach which reasons over a very large knowledge base. Human beings of course will fill this knowledge base manually in the beginning but after there is enough knowledge then piecing together a smart contract will look like fitting together puzzles. So you might want to tell the graphic designers to use the puzzle shapes for their art representing smart contracts and big data would represent the collective knowledge base expressed as a bunch of known facts. Reasoning would look like a cloud of various logic symbols being manipulated with some numbers.

Artists can take inspiration from this article: https://www.newscientist.com/article/mg23331144-500-ai-learns-to-write-its-own-code-by-stealing-from-other-programs/

As it explains it in a way most people can grasp. Yes Tauchain will write at least a portion of it's own code. The automated programmer would be a use case of an "exocortex" for people aware of what that is.
