Friend, critic and artist Nguyen Nhu Huy has written an article on some of the foreign artists working in Ho Chi Minh City. The article, Arts Framework in HCMC: Some new backgrounds, is in Vietnamese. Huy also maintains a bilingual website and blog.

I did a search from variations on the spelling of my name. Steimatter (rather than Streitmatter) revealed this article I hadn't seen before. Streimatter unearthed this article I co-authored for Tuoi Tre.
