From David Ackley, Liquidware, and Illuminato Labs comes the Illuminato X Machina project -

It’s a small “motherboard cell” that can interchangeably link and connect up to other cells, either rightside up or upside down, to adaptively route packets and power to its neighbors, like a grid of biologic cells, passing nutrients and resources to their neighbors. Also, each board can program its neighbors using a dynamic bucket-passing bootloader that allows any given cell in the grid to over-ride or re-program neighbors.
[…]
Each cell runs a 72 MHz ARM processor with 56 digital I/O pins, and the ability to accept power from any one of its 4 edges. This means that the cellular grid can expand in any direction, and the reversible interconnections mean it can grow like a crystal in any orientation.
