PG Calculator is a powerful scientific calculator and an excellent replacement for standard calculator. It offers a fully customizable user interface and resembles a real calculator. It works in Algebraic and RPN modes, recognizes real and complex numbers, and allows vectors manipulations. It supports up to 120 units of measure with the ability to make conversions between consistent units, and allows input in binary, octal, hexadecimal, and exponential formats. Eighty built-in algebraic, trigonometric, hyperbolic, logical, conversion, and statistical functions are provided along with a list of commonly used mathematical, physics, and chemical constants. Simple financial calculations are possible with built-in Time Value of Money Solver.

Electronic Engineering Tool is a Web-based tool that includes an electronic formula calculator and converter functions. It very useful when working with electronics, both for engineers and amateurs. For example, it includes converters for dBm-to-Watt and Fahrenheit-to-Celsius, and it can calculate Ohm's law, filters, thermal resistant C/W, SWR, coil inductance, capacitor capacity, and more.

Motorsport is a project with a clear goal: to create the most realistic vehicle simulation possible. This includes cars and trucks, which can be driven using common input devices such as keyboards and steering wheels. It limits realism to what the hardware, and is intended for hardcore driving simulator fans. This means that it will try to have realistic physics, but not necessarily 'playable', 'easy', or 'fun' physics - these characteristics will depend on which vehicle is driven and on what a person is trying to drive it.
