4D Bowling

[PatrickPowers]

What would a 4D bowling alley be like? I figure the pins would be arranged in a tetrahedron with three of the vertexes in the wx plane and the fourth closest to the bowler. Have a pin at each vertex and in the midpoint of each edge. With four vertexes and six edges that conveniently makes for the standard ten pins. The bowling alley is a triangular prism surrounded by a gutter. The standard layout is one foot between the center of each pin and its nearest neighbor, and 4.75" diameter for the pins. Doing the geometry I found out that this would not give the domino effect needed in bowling. The distance between pin centers has to be reduced. Eight inches would do it.
