4D Draw
4D Draw is a simple vector-graphics appthat lets you draw 4‑dimensional figures. It represents eachpoint's first three coordinates in the usual way, while using colorto represent the fourth coordinate. A built-in Help menu includes a“How to draw” page for an easy start, followed by a page of “4Dconstruction ideas” to set you on your way towards visualizing4-dimensional space.4D Draw is intended for geometry students who want to learnto visualize 4‑dimensional space. People looking for a morerecreational introduction to 4D should begin with 4D Maze instead.People looking for an even more recreational introduction to modernconcepts of space and symmetry may enjoy the Torus Games orKaleidoPaint.Keywords: 4D, 4-dimensional, drawing, vector graphics, geometry,visualization, hyperspace, 4-space
Torus Games
Eight familiar games introduce children ages10 and up to the mind-stretching possibility of a “multiconnecteduniverse”. Games include: tic-tac-toe, mazes, crossword puzzles,word search puzzles, jigsaw puzzles, chess, pool and gomoku. Whileplaying the games, kids develop an intuitive visual understandingof a model universe that is finite yet has no boundary. Players whomaster the games in 2D may enjoy the extra challenge of solving 3Dmazes and playing 3D tic-tac-toe in multiconnected 3D spaces. Eventhough the games were designed with kids in mind, adults interestedin topology, geometry and cosmology have also found them enjoyableand enlightening.Keywords: geometry, games, topology, torus, Klein bottle, 3D, maze,crossword, word search, jigsaw, chess, pool, tic-tac-toe
