What pattern do you work with?

You can play around with this arrangement: simply left-click on the symbols and drag to arrange them as you wish.

Note that this only works with Internet Explorer and derivatives (such as Avant) and Opera, and I have no idea why. Frankly I have no idea how it works at all!

I learned how to do it once, but now I've forgotten. There's a moral in that somewhere...

  Check out whether the arrangement fits with the environment in which you work.
• Do your students see it the same way?

(I know it changes from moment to moment, but what is the default arrangement?)
