We made the unusual set with the unique design, so don't think that these polyhedrons are only a prank.  It is not a prank, but a useful set for all games, even the most serious. These are very merry dice with the touch of grotesque macabre and when you roll them, you can hear very very quiet first tones of Bach's Toccata and Fugue in D Minor. Yes, that organ music from horrors!
