played with this yesterday its really interesting , and as you say opens up a lot of possibilities...
but I think perhaps more exciting is the underlying technology Xebra

Sam/Cycling 74, has done another great video explaining this.
it all is pretty straightforward JS, so could be a lot of fun to play with ...
(though Im now waiting for Cycling74 to release the 28 hour day package )
