When selecting wood for sculptures in interactive installations, durability, texture, and sustainability are key. Here are the top choices:

1. Oak: Known for its strength and grain patterns, oak is ideal for large, tactile sculptures. It withstands frequent handling and weather conditions.

2. Walnut: A favorite for fine detailing, walnut offers a rich color and smooth finish, perfect for intricate interactive pieces.

3. Cedar: Naturally resistant to decay, cedar is excellent for outdoor installations. Its aromatic scent adds sensory appeal.

4. Basswood: Soft and easy to carve, basswood is great for participatory art where visitors can touch or modify the sculpture.

5. Teak: Highly durable and water-resistant, teak suits high-traffic interactive exhibits, especially in humid environments.

For sustainability, opt for FSC-certified woods or reclaimed materials. Each type offers unique tactile and visual qualities, enhancing the interactive experience.
