Triangles have natural immunity to diagonals.

Playing with diagonals can be fun whether you're making Stars or Movies.

If the numbers aren't relatively prime, then you won't use all the dots. Just move to the next dot, and make a second star, and third, if necessary.

Stars R Ours

This one was a little late because I redid the original version.
Originally, I had the regular polygons included along with all the diagonals, which formed all the stars.
At the last moment, I realized that Little Miss Tree was asking for a pentagram, which wasn't really the mood I was shooting for. Back to the drawing board.

And for once, I can actually use that expression in almost the way it was originally intended.
