The creators of Zentangles, Maria Thomas and Rick Roberts, enthusiastically promote the advantages of guided doodling, describing it as "fun and relaxing. It increases focus and creativity. Zentangle provides artistic satisfaction and an increased sense of personal well being."They sell kits comprising high quality paper tiles, pens and pencils, an instruction book and DVD, and patterns for "Tangles". The Zentangle empire appears to be growing rapidly, with classes and weekend seminars on offer, and even a program to train licensed teachers.
It's a brilliant idea, and my congratulations to Maria and Robert on their entrepeneurship. Much of their work, and that of their students, is decorative, but is it Art?
