Slashdot pointed out a prototype modular motherboard; a big mobo is made from snapping together a bunch of little ones: <a href="http://www.wired.com/gadgetlab/2009/08/modular-motherboard/">http://www.wired.com/gadgetlab/2009/08/modular-motherboard/</a><br>

and one of the contributors to the project [says] “We have a CPU, RAM, data
storage and serial ports for connectivity on every two square inches.” '<br>...<br>Each X Machina module has a 72 MHz processor (currently an ARM chip), a
solid state drive of 16KB and 128KB of storage in an EEPROM ... chip. There’s
also an LED for display output and a button for user interaction.'<br><br>The modules share power & data through a single connector, recognize the presence of neighbors and can load each others programs automatically.<br>
<br>If the connectors are the usual male/female (not certain from the picture) then snapping them together would be a bear, since the vertical pair of pins wouldn't be aligned when the horizontal pair hasn't been snapped in yet, and vice versa.<br>
