Here's what I did:

1) Make a NURBS sphere
2) Apply the shader to it
3) Set your Render Globals to render an image that's 200x200 in size
4) Render the current frame
5) In the Render View, drag a marquee around the image
6) In Render View, select View>Grab Swatch to Hypershade/Visor
7) Middle mouse button drag the selection over to the swatch in Hypershade

That worked for me.
