Abstract:
1. A first puzzle unit comprising: a first puzzle unit assembly including a first support member and a second support member projecting from a first inner surface of the first unit assembly, and a first triangular unit face on an outer surface of the first unit assembly, with a space between the first support member and the second support member defining a first linear slot; a second puzzle unit assembly geometrically identical to the first unit assembly, including a third support member and a fourth support member projecting from a second inner surface of the second unit assembly, and a second triangular unit face on an outer surface of the second unit assembly, with a space between the third support member and the fourth support member defining a second linear slot, the second unit assembly, rotated relative to the first unit assembly such that the second linear slot aligns with the first linear slot, a portion of the first support member overlaps with a portion of the fourth support member, a portion of the second support member overlaps with a portion of the third support member, and a common edge defines an angle of about 60° between the first unit face and the second unit face; a third removable unit face engaged with the first support member or the fourth support member such that the third unit face occupies a plane substantially parallel to planes occupied by overlapping first and fourth support members; and a fourth removable unit face engaged with the second support member or the third support member such that the fourth unit face occupies a plane substantially parallel to planes occupied by overlapping second and third support members.
