Wow, what a lot of 'pats on the back'.
Thank you John, Gavin, Jim, Ian, Monica, and Steve.
To tell you the truth, I am apprehensive yet confident at the same time. But simply, my goal is to make it work; and to work for a long time.
Part of my apprehension comes from when I was a teenager who wanted to build a moving sculpture. I remember becoming crestfallen when I read from a famous artist 'that a sculpture should not be made to move'. The reason was that if it stops moving its purpose ceases, and if it cannot be repaired it becomes useless. Then many years later I heard a counter quote from an artist who said 'that a piece of art is not complete if it cannot stand on its own'. The reason was that it should not have to rely on a frame, on a light setting, or movement, etc.
The other part, is my confidence. This simply comes from a belief I picked up from a Star Trek episode. "Nothing is impossible. It only seems impossible because we don't yet understand how it could be possible". Or something along those lines. So the word 'impossible' is not in my vocabulary. So when somebody says it is too difficult, or impossible, I suddenly think I am talking to a stranger.
However, I have also learnt to not worry about the results. Focus on the process and the results will take care of itself.
I am hoping to create an interesting diorama so that the display can stand on its own (without power to it). This is where I know I will be relying heavily on the forum members. I am hoping you will be able to give me advice and suggestions when it comes to the landscaping, etc. you all have the experience, where I don't. However I have to warn you, I can be stubborn in my ways, so please don't get upset if I don't follow somebodies suggestions.
Thank you for your support.
