I see many material elements both in Polymer and AngularJS Material. As I know, both of them are google's products about Material design, Are there any relationships between them? Are there any plans for Material for Angular v2?
Material design is a new design language spec that many frameworks, widget libraries, and 3rd authors can adopt and implement.

(material design) elements should be very similar to their JS counterparts. Ideally, there would be no port of the elements themselves, but true dart/js interop is lacking right now.
