Hi ditter - to me it looks like a Rhode Island Star
http://www.quilterscache.com/R/RhodeIslandBlock.html set on point, alternating with the classic Snail Trail here called Monkey Wrench
http://www.quilterscache.com/M/MonkeyWrenchBlock.html. The set in triangles which include the border stars take a little more studying to work out though! Hope this helps - it's beautiful, I saw it on the other thread and wanted to make it too!
