I've fallen in love with this block, and have lots of bright fabrics to make it with, however, the person who posted it on Flickr (bemused.typepad.com) called it the 'whirling dervish' and whenever I search for that, I come up with different patterns.

Any one know a more common name for it, and especially where I can get a pattern/instructions?

Many thanks for your help ahead of time!
