Gill:  Thought I would try your magic lantern idea on a fractal of mine and I got this.  Using Wombo the only words in the prompt were, "magic lantern".  Not as pretty as yours but kind of the same result.  I am sure I could have refined it to make it better but just wanted to see what I could get with just those words.  

Got this lantern from an image of mine in Wombo.  Not the same effect but I liked it better.  Only words in prompt were "magic lantern".
