The setting:

• Two devices. The primary device has an active MotionRuntime and a Tossable interaction. The secondary device has a collection of sliders for augmenting the Spring's configuration.
• Changing the sliders on the secondary device should cause the reactive properties on the primary device to be changed.

This demo will lay the foundation for our cross-device tweaking functionality.
