My significant other was recently given one of these Woodbaby shoulder puppets by a friend of hers who frequents renaissance faires, where the Woodbaby is apparently a popular commodity. The puppet features a strong magnet in its base that mates with a curved metal plate that goes under your clothing and keeps the figure firmly perched on your shoulder. The mechanical control cable (which, per this thread discussing a DIY version, is an R/C airplane control surface push-rod) runs to a simple controller that can be concealed in a pocket and manipulated to make the figure look around in a surprisingly life-like manner. More elaborate versions have additional controls like wings and blinking, light-up eyes. Flickr user JeffreyWiden made his own. Would be cool to see an electronic version with a wireless controller.
