Paintable Computing Project Summer 2004 Virtual self-assembly is predicated on -- and motivated by -- the notion of a “Turing substrate” . We use this name to describe a 3D volume populated my a dense irregular rmesh of logic-enabled nodes that are computationally universal This abstraction is a straightforward extension of work that models nature as an irregular mash of fine grain computing elements, each with task-specific physical hardware running a limited internalized procedure. For errant chip designers like myself, the notion of a Turing Substrate is simply an admission that today, you can fit a 32-bit Palm-class computer and a quarter meg of SRAM into 2 square mm of die.
