iridescence effect

[omichon]

I was wondering if the Node Editor would allow to achieve some nice iridescence like on soap bubble for exemple ?
All my tries are unsuccessful for now :thumbsdow
Any idea would be welcome !

Just a base node tree to begin, you could use other
noise for gradient input and other colors too:


Denis.

Edit: there are some specular/transparency/reflection values in the current
surface editor.

Well, I was expecting this kind of tree. I tweaked some nodes along the same direction but I hope I will have more chance with yours
Thanks a lot, Denis :thumbsup:
