FrAid (Fr[actal] Aid) is a programming language that is appropriate for mathematical computations, visualization, batch processing, and more. It features both a standalone application that provides a programming environment for the language and a system for integrating the language with Java. The Java interface allows mathematical equations and formulas to be used with Java code, making it easier to process numerical computations, symbolic computations, imaging, CAD, and more.

Asymptopia Flashcard System uses Motif and LaTeX to produce, manage, and use attractively formatted flashcards. You load some or all of your "collections" and set the timer for pop-up frequency. The GUI interface and "Collection Manager" make creating and modifying flashcards as simple as pushing a single button. A knowledge of LaTeX is only required when entering special symbols.

Mathnetics is an API for creating advanced, interactive, Web-based mathematical applications. It defines various important mathematical objects that are inter-related and on which many numerical calculations can be done. It also features rendering of 3D objects onto an SVG canvas (to do so, it includes certain utilities such as browser sniffing, DOM node selection, and DOM readiness detection), which is quite robust. A few basic 3D objects are given (Line, Sphere, Cube), but the user can define any 3D object desired as per the specification.

Pulga is a program for numerical simulation of dynamical systems. It is designed to provide a way for students and researchers who study dynamical systems to model them on a computer and analyze them numerically without the difficulty of traditional computer programming languages.

Lambda is an interactive Lambda calculus interpreter. It reduces lambda expressions and converts them into the S, K, and I combinators (ext). It has the ability to associate names with lambda expressions (def), load definitions from a file (load), and list current definitions (list). Lambda expressions representing integers are automatically defined as needed. Many interesting combinators are provided in a definition file. Various settings are provided to influence the way reduction and extraction are performed (set). A short manual is provided showing how lambda works.

TheCurves is an application that plots a parameterized family of curves based on algebraic formulas specified by the user. It is meant as an educational tool for mathematics, physics, and engineering. When the program is run as an applet in a Web page, the plot parameters and formulas are configurable by HTML and dynamically scriptable, so that the applet can be initialized to present a specific plot when the page is opened or to change plots when the user clicks on a control in the Web page.

Math Volcano is a Javascript Web application for memorizing multiplication tables through "12 x 12." Individual and cumulative clock time information is shown in a table. Each "level" can be repeated until the clock times are satisfactory. Cookies are used to store the clock time information for five days after the session. Student interest is increased by allowing them to repeat individual levels to improve their clock times. After completing all levels, the sleeping volcano awakens!
