Marionettes and consoles

An old-fashioned marionette lets the puppeteer control all four limbs, swivel the puppet, and move it in three dimensions - using only one hand (*). Why has nobody adapted this as a computer game controller? [Or have they?]

It doesn't sound technically any more difficult than a wiimote. You could hold one in each hand, and put all the buttons you want on the underside. Plus, we might get to see some wizened Czech puppeteer beating all the kids.

(*) At least, I think it does. Corrections from anybody who has tried using one of the things?
