It’s raining today and that puts a hold on my painting operation for now.
The next project on my list is the skeletal organist. I have an organ I got for free on Craigslist and I want to have a bucky skeleton sitting at it “playing” a song. I need to think about how I will make the arms move. I don’t really need the hands to touch the keys or anything, but I do want the arms to have some amount of up-and-down motion to them.
To do this, I was thinking that I don’t really need the entire skeleton. The skeleton will be wearing a costume, so the only visible parts will be his head, hands and his feet. This frees me up to devise just about anything I want mechanically to achieve the movement I need.
I’m going to spend the afternoon drinking beer, brainstorming, and researching how I can do this. 
Anyone with any ideas or links is welcome to chime in.
