Totally useless but ...

... the report of the rediscovered David Carter tutorials blew on a dying ember in a hidden recess of my mind.

In older versions of excel there are a number of for want of a better word "secret cells" that have strange things in them (I think they were called Easter Eggs) One I seem to remember had a three D type scene where you skimmed over the landscape and cam to a mountain that had something carved in it, I think it was credits for the programmers. 

Do they still do this, and does anyone know the cell reference, and do they know any others?
