Older Birthday Stars, From When I Was Younger

Posted on 12 January 2016 by RobertLovesPi

I started this blog in July of 2012, so the birthday stars I made in January 2012 (when I turned 44) and January 2011 (when I turned 43) did not appear here in those years. I found them, though, and will post them now.

The first two are different colorings of a 44-pointed star, from January 12, 2012, the day I turned 44:

These three are different color-versions of 43-pointed stars, from a year earlier — January 12, 2011:

I turn 48 today, so please visit the post right before this one, if you’d like to see this year’s birthday stars. =)

It can sometimes be difficult to distinguish between kites and rhombi. In this case, the edges between rhombi which meet five at a vertex are slightly shorter than the other types of edges here, making the yellow faces here, of which there are sixty, kites. The blue equilateral triangles are twenty in number.
