Unrolling grid - Solved

Mosk the Scribe

Is there a simple way to unroll a grid or plane using modifiers?  I think I'd done this a couple of years ago - but can't find the file and having a hard time replicating method. I think it was something using modifiers like bend and twist - and you could unfurl from either end by simply animating one or two properties.

Thanks for any pointers.

Never mind . . . 

A bit more tinkering and found you need to set the Bend angle higher (360, 720) and then just animate limits.
