Instructions for dancing funnel technique?

[Zing]

Let me know if you know of any good written instructions for the dancing funnel. I have found awesome YouTube videos which are helpful. And I know how to calculate volume for specific molds. I'm more interested in the ratios or amounts of the outline color and the inside color. Thanks.

The Dancing Funnel technique was featured in one of our recent monthly challenges, and the challenge thread has some excellent written notes made by members to describe how much batter to use for each colour.
