Warbreakers - MacGuffin Development

Trying to decide upon which Macguffin to use for the german wonderweapon, I doodled trooper designs based on various ideas

My favourite idea was the two-man lightning-gun team at the top of the second image, but I kept doodling and was struck by the idea of a radio-controlled drone-type weapon (this came from the guy bottom left of the second image, with the massive backpack radio).  I've decided that this is the wonderweapon for me, as it a) is pretty realistic (certainly compared to some of the ideas I came up with) and b) allows me to invoke every geek's favourite genius, Nikola Tesla, as the brains behind the technology (since he demonstrated radio control back in 1898).
