Grand challenges in spatial-temporal computing on image flows

Summary form only given. One of the most difficult tasks, since the invention of the computer, has been the solution of nonlinear wave equations. Now, the broader problem is to make a computer operating on image flows as data and having elementary instructions as solving nonlinear wave equations. Interestingly, almost all of the living sensory systems have similar anatomies and physiology models. The cellular wave computer is doing this exactly. Their implementation is presently mostly 2D. A major challenge is a way to make it in 3D, and how to make it in nanoscale or by using non-electronic materials. These could lead to a new understanding of the complexity of computing, as well.
