Love this model and even more the invisible hand version. You should work for Lego as these mocs are perfect in size (parts) to make it a commercial succes. Concerning LDD : If you have some building instructions, there's no need to make them public by putting them for free on the web. You can ask a smal donation for the effort and time you have put in it. I suppose that would only be fair. And it's true that LDD instructions are not always that logical - to put it in a nice way - but I'd build the model first (in real bricks) , so I could give some support to those who are making a donation...Anyhow if you're just a little used to LDD there is always a way of getting around the "unlogical" problems you incounter once building. It would be nice if you would share the model with me. I would only use it for private use (no pictures or whatever on my moc pages site) Thanks
