The disk contains an art gallery in which over 600 of Escher's illustrations can be browsed in chronological order. Works can be viewed in chronological, selective or random order, with a search function allowing users to search for works by name, theme or object. In The Animated Escher, six animations based on Escher works are featured, including those based on his Möbius Band series. Spheres allows the player to view several Escher works, with the cursor featuring a circular lens that slightly distorts the image. The disc also features three interactive tools and games: in Tessellation Workshop, users can edit interlocking mosaic patterns using a tool to modify nine of Escher's tessellations. Users can modify the patterns by bending the lines or altering the colors, and can save and print the images. Convex and Concave is a game in which players are presented with perspective puzzles., where the player is presented with a surface and must decide whether that surface is convex or concave by placing an item with a corresponding perspective into the correct position. The mode features a time limit and several difficulty modes. Impossible Puzzles is a 3D puzzle game, requiring players to assemble cubic puzzle pieces to imitate a complete shape onscreen.

Development of Escher Interactive began in 1994, led by executive producer Michael Chanowski and Henk Alles of Dutch development studio Eyeware Interactive. Puzzle designer and author Scott Kim, who developed the Impossible Puzzles game, stated the design was based on his previous puzzle title Heaven & Earth, basing several of the models from Escher works including the impossible cube and stairway. The game was developed in co-operation with the Escher estate, and published jointly with Byron Preiss and art publisher Harry N. Abrams Inc..
