I was thinking about how I could make a 'plausible' technomancer and I like the idea of having the shell of a machine or computer driven by a 'techomatic field' that acts as the motherboard/processor/whatever for the machine. So all the circuitry there and the technomancer just drives the bits via thought or pre-installed thought. For example having a robot walk would have all the wires and pistons controlled by this field, and the field spits out commands to the power sources to pump that piston this much, this piston that much etc and have those as fundamental commands pre-established by the 'technomantic field' and all the technomancer has to do is think 'walk there' as theyve already installed the basic functions with this field. 

I want it to work in a semi realistic way if I going to use it and this is what Ive been able to come up with at any rate. Any criticisms/suggestions?
