How COOL is this?

I just found this earlier today, while reading through American Patchwork and Quilts.  A vanishing design wall!  Where or where was this a few months ago when I bought one of those Cheryl Ann Design Walls, which I do not like very much.

The roll up feature would be perfect over my double door closet, wasted space that I could be using but can’t block!

I’d love some feedback on this if anyone owns one.
