Many of the most beautiful things in life are squares, including paintings by Ellsworth Kelly and gold-leafed statues of the number 36. Add some squarage to your life with today's Groupon: for $10, you get a 6"x6" custom photo tile (a $24.95 value) or $25 toward more expensive options at TilesandSmiles.

TilesandSmiles translates JPEG or TIFF digital image files into a crisp printed image on durable 6"x6" ceramic tiles. Specialized polymer seals in the vibrantly colored inks, preserving visual evidence of nuptials or pogo-race photo finishes. Each four-cornered keepsake hangs on a wall by a hook embedded in its back—the tiles are fragile and shouldn't be cemented into floors, used as coasters, or juggled by amateur circus performers.

Alternatively, Groupon holders can opt to use $25 toward a more highly valued player from the company's tile team. Enshrine a super-sized image on an 8"x8" ceramic tile ($32.95) or acquire a glow-in-the-dark tile ($29.95) that shimmers more brightly than 10 mayonnaise jars full of fireflies.
