Motion Path Problem For Nurbs Cube Snake! Help Please! Goin Nuts!

[mayabi]

Okay I know I read the posts on flipping and how to combat that with making a secondary curve with a locator I also read and down loaded Joojaas'
ribbon.ma file to see if maybe I would have a better time trying to animate it that way but I'm just having a hard time. I posted my .ma file online Iand i'm wondering if someone can look at it and give me any suggestions. The problem I'm having is that the snake or train object is quite long and the locator it follows can't compensate for the entire length of the object. The file I uploaded is one of many I worked on and I know there's gotta be an easier way of doing what I want it to do. The end result should be the snake comes in to form a logo in the shape of a combined CP. Any help will be appreciated! heres the link http://www.almostreal.com/test1

Well theres sevral ways you can attack this (yes is saw your pm just was busy right then):

You can use a curve on plane, and then path anim. Making this plane with a animated snapshot is rather easy. (tahts what i did)

You can use a joint chain for this, combined with some other etras such as spline if it would make this alos easy.

You can use a dynamics simulation to lag the parts nbehind and use a unflipping path anim (its easy to know when to flip)

Or simply seek the driection that you do not traverse, then put that as the up vector, and just use what you have now.
