Current Projects & Installations

Sand Globes Worldwide
Since discovering a technique for making near-perfect spheres from just sand and water in 2000, I've used sand globe making as an avenue to connect people with each other and with coastal areas. Free public beach-cleanup events combining sand globe making with environmental stewardship have been a great success. I've launched an effort to spread sand globe making worldwide using social media and a "how-to" video that has had thousands of views. Read more.

San Francisco Children & Nature
Since 2018 I've been part of the Nature Connection Design team for San Francisco Children & Nature, a cross-sector collaborative of over 30 government agencies, non-profit institutions, and community-based organizations striving to ensure that every child has opportunities to play, learn and grow in nature. One of our projects has been to prototype and develop design criteria for Nature Exploration Areas such as this one at Rolph-Nicol Park. Learn more in this report on our first three years' work.
