Just cause you asked (okay, so just Deb asked), here's the mosaic we made in worship on Easter. It was fun smashing the old plates, and fun to put them together, too.
This is the before-grout pic:
At first, I was kinda bummed that it's hard to make out the cross, but I've grown to think I really like the way the cross is broken apart, sent out, re-made with our pieces.
(We used a water-based liquid-nails-like-but-less-toxic adhesive from the hardware store to glue the pieces on individually, so we didn't have to figure out how to spread mortar during worship, or keep in wet. I'm pretty happy with how it all worked--remarkably smooth for involving 140 people in creating it during a "regular" hour-long worship gathering... The lumpiness added significant challenge for my grouting work later, but I don't think it ended up too bad. It's a bit lumpy, though--so it wouldn't really work well for a table surface.)
