AcaStat statistical software is an inexpensive and easy to use data analysis tool especially designed to help students develop analytical skills. Whether a teacher, researcher, or a student you will find that AcaStat is a simple solution for your basic analytical needs.

Calculus Problem Solver can solve differentiation of any arbitrary equation and output the result. It can provide detailed step-by-step solutions to given differentiation problems in a tutorial-like format. On top of these, it can also initiate an interactive quiz in which you can solve differentiation while the computer corrects your solutions.

Desktop Sudoku - Play thousands of sudoku, sudoku-x and tridoku puzzles.

Graphing Calculator 3D is an easy-to-use tool that plots 2D and 3D functions.

- Plot functions: y=sin(x) or z=x+sin(y)
- Plot coordinates tables.
- Generate x-y-z coordinates tables from functions.
- Rotate and zoom in the graphs in real-time.
- Shade 3D graphs for better visualizations.
- Customize graph resolution and appearance.
- Customize axis.
- Customize computation precision and decimal places.
- Save, copy and print graphs.

Make animated swirly patterns which change shape. You can use real materials such as gold, pearl, ruby. Many demo patterns included for the screen saver (over a hundred) and you can make new ones to add to it. The classical Lissajous curves are traced by a point swinging back and forth in two directions at once - Lissajous 3D follows this idea into three dimensions, You can set the lighting to sunset, sunny day, dawn, dusk etc.Includes a wizard suitable for young children, which can also be used by older children and adults. You can use its companion program Fractal Tune Smithy to generate intricate fractal music to accompany the saver - you can also set the patterns to respond to chords played in FTS. You can also accompany the screen saver with music in other formats (midi, mp3, wav etc) or select tunes at random from a folder or cd. Many pattern transforming effects included too, some related to things that happen with real world Lissajous patterns, or mathematical transformations of them - pattern drift so they continually change shape, gravity, magnet, inversion (turn inside out), transparency, friction, etc.

Make animated swirly curves which change shape. You can use real materials such as gold, pearl, ruby. Many demo curves included and you can make new ones to add to the screen saver. Includes wizard suitable for young children, randomiser, and background music. The classical Lissajous curves are traced by a point oscillating in two directions - Lissajous 3D takes this into three dimensions. Also has spirograph - those patterns generated by wheels within wheels - but in 3D. You can set the lighting to sunset, sunny day, dawn, dusk etc.
