A teaching aid for binary programming language contains: a Rubik's cube including six surfaces. Each side has fourth corner pieces, four side pieces, and a center piece which are rotatable. Each of the four side pieces is defined among any two adjacent corner pieces and the center piece, and the center piece is defined among the four corner pieces and the four side pieces. The center piece has a calculation sign, and each of the fourth corner pieces and the four side pieces has a binary number.

A mechanical computing system configured to serve as an aid in learning fundamental aspects of coding. The mechanical computing system including a substrate having a flow path between an upstream portion and a downstream portion, and a plurality of repositionable programming members pivotably coupled to the substrate and configured to guide and interact with units dispensed along the flow path from the upstream portion to the downstream portion, wherein a first programming member is configured to pivot relative to the substrate upon interaction with a unit traversing along the flow path, and wherein a second programming member positioned upstream of the first programming member is configured to pivot relative to the substrate based on feedback from the first programming member.
