I like this one. Essentially, it's variations on a theme. Perhaps I add a twist and see if it will be as pretty.
On a side issue, tinyurl.com/p3c6mdh/newPentTri2.svg didn't work when I put https which redirects to https://c3b8f482385fc05f71d246e2e23a26cb99a3c770.googledrive.com/host/0BwD1YaggiIIAY1gxNEJEa2JKNlU/newPentTri2.svg which needs the https. Not surprising but there certainly is a lot of details to juggle--at least when you are doing posting content on the cheap... Of course, if Blogger simply let me upload my svg files I wouldn't have to do any gymnastics... I ended haven't to use my own host.
