Investment Equals Toast

Just reading this news about a gadget that lets you burn different images on your piece of toast.  Cool!  Silly!  Coolsilly!

Of course, my thoughts went back to the news story a couple of years ago, about the piece of toast with an image of the Virgin Mary that sold for close to $30,000 on ebay (a transaction that formed the centerpiece of a contracts exam I gave that year). 

Does this new technological development render the Virgin Mary toast valueless?  Or does the original Virgin Mary toast retain a special cache due to the religious iconography and the fact that the image appeared spontaneously?  Of course, one could say that even the original sale on ebay really did serve to show the subjectivity of value (a point that very few students made on the exam, but which I had hoped more would address).
