A three-dimensional logical cube has 6 faces in the same configuration of Rubik's Cube (trademark). A three-dimensional logical cube has an N×N array of cells on each face. Each cell on a three-dimensional logical cube has a numerical value, solid and hollow dots, solid dots, or shapes, on it. A 2×2×2 cube has four numbers from 1 to 4 on its face; a 2×2×2 cube has two solid dots and two hollow dots with the same color on its face (2×2×2 alternate embodiment); a 2×2×2 cube has 1 dot to 4 dots on its cell (2×2×2 alternate embodiment); a 2×2×2 cube have same kind of shape on its face (2×2×2 alternate embodiment); a 3×3×3 cube has nine combination numbers between 1 to 12 on its face; a 3×3×3 cube has nine numbers from 1 to 9 on its face (3×3×3 alternate embodiment); a 3×3×3 cube has either a blank cell or a dot on its face (3×3×3 alternate embodiment); a 3×3×3 cube have same kind of shape on its face (3×3×3 alternate embodiment); a 4×4×4 cube has sixteen numbers from 1 to 16 on its face; and a 5×5×5 cube has twenty-five numbers from 1 to 25 on its face; The present three-dimensional logical cube when successfully solved, for numerical cell cubes, all six faces, and nine rows (six rows for 3×3×3 cubes) of adjacent cells located on four adjacent faces (two adjacent faces for 2×2×2 cube and three adjacent faces for 3×3×3 alternate embodiment) will have difference numerical numbers on its cell (no two numbers are alike); for shape cube, all six faces will have same shape for each cell on the same face; for solid and hollow dot cube, any faces will have the two solid dots and two hollow dots on its for all six faces; for solid only dot cube (3×3×3), any two opposite faces will have total of seven dots for all six faces; and solid only dot (2×2×2), each cell on the same face has 1 dot, 2 dots, 3 dots and 4 dots for all six faces, and four adjacent cells located around two faces will have 1 dot, 2 dots, 3 dots and 4 dots on its cell. The present three-dimensional logical cube is more challenging than the Rubik's Cube (trademark) with 2×2×2 the simplest logical cube to 3×3×3 challenge, 4×4×4 more challenge, and 5×5×5 which is the most challenge logical cube to solve.

An electronic musical page turner is consisted of a LCD (liquid crystal display) display, triple foot actuator switches, and an external personal computer, scanner, USB portable storage device, and USB wireless electronic pen.The system transfers and displays of electronic score music files using many available software and electronic music files format such as PDF, Scorches, Solora, etc . . . The musical score data can be exchanged between the LCD display and a personal computer through the use of foot actuators and command functions on LCD display's control menu. The LCD can display two pages of music score in landscape viewing mode or one page in portrait viewing mode. Foot actuators are manipulated by the performer to progress the sheet music score on the LCD display. The performer can turn the electronic sheet music score to next page, previous page, or home page by pressing specific foot actuator. Likewise, the performer can edit or add hand written notation onto electronic sheet music score by using USB wireless electronic pen, and scan personalized hard copy sheet music score into electronic file.
