It's just a posh name for doodles, but check out the amazing ones on flickr and of course there is a website where you can pay £25 for a kit!!!
But all you really need is to have a read of zentangle.com (what else?) a nice pen and a piece of paper.
Mine aren't true zentangles, to be 'zen' with your 'tangle' you need to use a black fine tip pen and 3.5 inch square white card and not the back of envelope while chatting on the phone.
But hey, I've never been one for following instructions!
