Null_Pointer Book Magnets

I thought I would try a new give-away promotion for Null_Pointer.  In addition to making book marks, I made up some book cover magnets.

  This picture below does not do them much justice, but they do look pretty cool.

  The size is standard business card.   Unfortunately the image is just slightly offset to the left and the binary code is not as visible as I would have liked.  But for only around thirty bucks for fifty, it was a worthwhile experiment.

  I could see one of these for each of my books, stuck to my car door like a victory tally on a WWII airplane.
