I usually find this glass-on-top-of-walls business ugly, upsetting and/or depressing, but for some reason this time around I was struck by how beautiful it is. All of these were discovered in various alleyways in San Miguel de Allende.
And a final glass landscape with a mixed message: "Peace and love to all mankind, but if you try to get into my house I will cut you to ribbons. . . love, Mary."
