Contributed by "William E. Emba"

Uses the fourth dimension as geewhiz terminology to explain a matter duplicator/unduplicator. Includes a tesseract. But if you ignore the story's explanation involving time as the fourth dimension for the rank pointlessness that it is, and substitute a genuinely geometric fourth dimension for the effects that happen (as in, reality has a bit of 4D thickness, and the contraption grabs slices) then it's not actually all that bad.

At least temporarily, this story is available for free on-line from I didn't put it there so I have no idea how much longer it is likely to stay before a copyright holder forces them to take it down.

Exciting News: The 1,600th entry was recently added to this database of mathematical fiction! Also, for those of you interested in non-fictional math books let me (shamelessly) plug the recent release of the second edition of my soliton theory textbook.
