Basic Zentangle:

• The Zentangle website
• The Zentangle Blog
• Tangle Patterns - Linda Farmer's ever-growing reference site
• This article on wiki-how is really very good, but the illustrations are quite misleading. Read the article and ignore the pictures.

Zentangle challenges:

• I am the Diva, CZT - a challenge every week, and a wide variety too.
• It's a String Thing - focuses on the string aspect of zentangle
• Weekly Zentangle video - focuses on a particular tangle each week

Not zentangle, but terrific:

• Mandalas on the web - Clare Goodwin's colossal site
• Vi Hart - great fun with geometry
