A well known thumbtack as shown at the top can be obtained from a simple circle and a pattern to it is almost obvious. 

But what would you say about a new version shown below it? Do you think it can be also obtained from the same circle? If your answer is "yes", then can you draw a pattern required to make such a thumbtack? Maybe it can be obtained from the pattern of the first one?
