How create stain glass window look

Glass Pebbles from the Dollar Store create this stain glass window look. This would be fabulous in the garden with the sun beaming through. It’s super easy to do-i glued the glass globs to the windows with E6000 and let it dry, then grouted it with a charcoal color sanded grout. i think the dark grout really makes the colored glass pop when the light shines on it. someday i want to do my bathroom window this way.
