A Hawaii husband-and-wife art team is turning hidden-detail murals into a growing business that now stretches from the islands to the mainland and the Middle East.

• Matt and Roxanne Ortiz paint under the name Wooden Wave, known for playful, eco-themed murals and illustrations of treehouses.
• Their work weaves in sustainability touches like solar panels, water catchments, skate ramps, and surfboards.
• They design each piece with hidden details meant to reward viewers who look closely.
• Painting partners since college, they have now finished close to 30 murals, most in Hawaii.

Outlook: With demand spreading beyond Hawaii, the pair look set to keep landing mural projects farther from home.
