Whipping - Lashing 'n getting Knotted?

The computer controlled flying system installed in the new Covent Garden Opera House is all computer controlled variable speed winches. It can do things that we only used to dream about. It does however have a human being on a dead man switch at all times. This is a situation where we seem to be far behind much of the rest of the world. Edit: There are a couple of good sites about automated systems, the company that put Covent Garden together is at www.stagetech.com Is that all there is? Well if that's all there is my friend, then let's keep dancing. www.tonymoore.id.au
