What do the geometric images mean?

Every Toosdays Prophet video, so far, has included four animated geometric shapes as part of the opening of each video.  The animations and sizes of the images have varied but the geometric shapes have remained the same... square, circle, triangle and star.

See the image below for an example of all four on the same page.

What do they mean?  

How are they related to the Words/Prophecies/Videos?

[Darned if we know.  Your guess is probably as good as ours.]

Leave your ideas in the comments below and we will see who comes up with the best answer.

Editor's update to original post:
Here is an idea we got from a reader (who was too embarrassed to add this to the comments section)...

You can't miss it.  The shapes used at the beginning of the Toosdays Prophet videos are taken from parts of the logo for Starbucks coffee shops.  See for yourself in the pictures below.  Clearly there must be some significance since they match up so well.  Plus, the videos started shortly after Starbucks updated their logo to the one below.  Coincidence?  I don't think so. 

With all the Starbucks locations around the world, it would make sense that they would expand into weirder, subliminal stuff like this eventually.  They probably thought no one would find out their scheme to influence the [highly caffeinated] minds of their customers and pull in potential customers.
