Capturing a spinmap display as frames for a movie or video

The function below makes a nice display of colors when the selected color map is rotated. Is there a way to capture the display as a set of individual images that can be % made into frames of a movie or video?

function spinpic( file )
   x = imread( file ) ;
   y = rgb2gray( x ) ;
   colormap jet
   imshow( y ) ;
   spinmap( 10 , 1 ) ;   % <- can I capture this as movie frames?
end
