Scott,
I cannot speak for Kresten, but your example is really gonna be helpful to me if and when I get back to a project that I currently have on the back burner. To date, I've not done a lot with graphics -or- multi-stack configurations using Rev, so this will be a fantastic learning opportunity.

Question: 
Is there any significance with the label field in each window?

At any rate, I really appreciate this particular example!

Best regards,
