stereop by mathematician John M Sullivan. This applet does Stereographic Projection of regular polyhedrons. User can choose any of cube, tetrahedron, octahedron, dodecahedron, icosahedron, and they are centrally projected onto a sphere. This sphere, is then stereo-graphically projected onto a plane. User can rotate the polyhedron, and see its image on the plane change accordingly.

Poly is another interactive 3D program that does polyhedra. This program contains a fairly complete set of regular and semi-regular solids that includes: Platonic, Archemedean, Prism and Antiprisim, Johnson, Catalan, Dypyramids and Deltohedrons. A special feature of the program is showing the solids as nets (graphs) and flat un-wrapped represenations. (the latter is good for making paper models of the solid.) Poly is a shareware. It's available for Mac and Windows.

RepTiles v.2.0.1 is a plane tiling shareware written by two mathematicians Daniel H Huson and ?.The program is capable of generating all possible periodic tiling of the plane. By the words of the authors: “… for interactively designing and systematically generating periodic 2-dimensional tilings and patterns, study symmetry and 2-dimensional geometry, if you are a mathematician, enumerate possible 2-dimensional crystal-structures, if you are a crystallographer or chemist, design complex and interesting patterns, if you are a designer, or explore a whole new world of fascinating periodic structures, if you are, well, just interested.” This program is a bit mathematical, but can be fun for layperson. It is a rare tool for crystallographer and mathematicians. URL: ftp://ftp.uni-bielefeld.de/pub/math/tiling/reptiles/.(Note: This program is from 1995 era. The software downloaded from the ftp site is missing data files, making the software not usable. I don't have a copy of it.)

MoebApplet, by Paul Murray. This Java applet does real-time interactiveMobius transformation. If you are studying Mobius Transformation, thisis the best applet for it. You can drag the fixed points, the poles, anda few other critical points in the plane and see the image change as youmove.
Interactive plane geometry software were made popular first by Geometer'sSketchpad at least back to 1994. It is a wonderful tool made possible bytechnology. Such program allows one to construct plane geometry drawingsdynamically, much in the way of Greek's “Ruler and Compass”. For example,draw a triangle with lines bisecting the 3 angles. They intersect in apoint called the incenter of the triangle. (which is also the center ofthe largest possible circle inside.) Now, you can drag the corners of yourtriangle to change its shape, and all your drawings change accordingly.Because of such dynamic power, a few theories on plane geometry have beenfound because of such software.
In the 1990s, there's only Geometer's Sketchpad and Cabri Geometry.In late 1990 came Cinderella, written in Java. But since about post 2000,there's a explosion of interactive geometry software. As of 2007, thereare more than ten of them (counting only quality ones), many of them arefree. They are all similar. They are all of high quality. Almost all ofthem can be saved as Java appletes so that it can be placed on the webfor students to use without needing extra software. Their features differslightly. Several of them are FreeSoftware. The following is a short commentaryof the ones i've actually used (except otherwise stated).

Simulations by Ishihama Yoshiaki. This program does lots of artificial life simulations. The program is a bit of crude. It works like a screensaver, where you just watch the interactions on the screen, and you can adjust some parameters. The program has simulations like flocks of bird, fish school, worms, swarms, and also simulate centipedes showing its gaits, and then spiders, ants, etc. It's basically a collection of simulations that satisfies the programer's curiosities himself. Not a full-fledged program nor polished, but very inspiring.

★ Poly-Peg 1.09 by S T Han. This puzzle is sometimes known as peg solitaire. You remove pieces on a board by jumping other pieces over it. The goal is to leave only one piece on the board. PolyPeg lets you edit your own shape of square or hexagonal board and set whether diagonal jump are allowed in square board. It also include a auto solve feature.
Pegged is a small mac program that plays Peg Solitare. It offers the traditional cross shaped board, but with 7 arrangement of end games. Written by Cary Torkelson in 1991, but still works great under Mac OS X Classic 2003.
★ Poly-Off 1.09 is another excellent shareware by S. T. Han. The game Poly-Off can be thought of as one type of cellular automata. In a square or hexagonal grid, you switch on or off a cell that will affect neighbor cells. The goal is to switch off all cells. I had lots of fun with this program.

★ Poly-Dol v.1.01 by S. T. Han. The puzzle in this program is similar to a commercial program named Cogito. You shift pieces on a board until all the pieces are in certain order. You can only shift pieces in certain row, column, or array of the board. There are dozen boards to choose for play and you can make your own board shapes. I find this program to be much fun. For Mac and Windows.

★ Poly-Tile v.1.04 by S. T. Han. This puzzel is similar to a commercial program named Tesserae, published by In-Line designs Inc.In this puzzle, Tiles of different design are layed over a board. You remove them one at a time by jumping (flipping) adjacent tiles of the same design. The goal is to leave only one tile on the board. I find this game too difficult. It's also hard to analyze because the random initial placement and designs. Like Poly-Peg and Poly-Dol, you can customize your board when you got bored with the given configurations.

StdMap.Standard Maps displays the dynamics of several area preserving mappings. It will also find periodic orbits, cantori, and stable and unstable manifolds of any (symmetric) periodic orbit.
The program is written by mathematician J D Meiss.
1DMap is another program by mathematician J D Meiss. It plots orbitmaps of various equations, including: logistic, cosine, cubic, exp, tangent,tent, circle. For each, one can plot the correspondig cobweb, bifurcationdiagram, and other statstical diagrams. The program is intuitive, but thereis no documentation or tutorial, so the reader must already be familiarwith the mathematics. Some textbooks on 1D dynamic systems are suggestedon his website.

ABC Map “abc, iterate a 3D volume preserving system”. It plots orbit maps of what seems various 3D formulas of significance.I don't quite understand the math here. However, this program is wonderfulin that it is like a screensaver with mesmeric images. Dots appears ina 3D box, and these dots fluctuate seemingly ramdomly that forms very distinctpatterns. It's like watching statics on TV, but the statics form unpredicablepatterns constantly. One can rotate the box. It is a fantastic programeven if one knows nothing about the math. The equation it plots has thesenames: Froeshle, Arnold, ABC, Integrable, Adriana, and others. I hope theauthor writes a minimum amount of tutorial to benefit the masses.

IFS Another program by mathematician J DMeiss. This program does the Iterated Function Systems. It comes witha tutorial on IFS. Nice. After reading the one-page tutorial, Iunderstand that IFS is as follows: we have n mappings of theplane. For each iteration, one of them is chosen by a givenprobability function. So, we start with some points or line in aplane, then apply the functions in each iteration, and plot thetransformed points or line accumulatively.
