I have an idea that is nibbling around the edges of my mind, but I can't quite work it out. It's close, it's tantalizingly close, but it's not real yet. Every time I model it in my mind, I get a little bit further down the design; but I keep running into a brick wall.
It just won't work.
Not yet, anyway.
But I can see it, and it's very cool. I hope that someday I'll be able to make it and show it to you. Unfortunately, there's just no way to photograph my imagination.
