There is a good online exhibition called Images in Light - Newly acquired Stained Glass at the Getty Museum. This is the same museum that had the 'Painting on Light' exhibit.
A number of the other exhibits are interesting from the point of view of applying outside ideas to stained glass. The exhibits I found most interesting ->
'Comic Art' has Daumier (I love Daumier), 'Casting Characters' is about portraits, Transforming Tradition - is about Ancient Motifs in medieval manuscripts, 'Heaven & Earth' featuring depictions of Christ and the Virgin.
Well worth browsing through...
