The software is designed as a simple accessory for teaching math. The program can represent the following objects in 3D space: regular prism (3 to 10 sides); general three-sided prism; special four-sided prism (adjustable inclination of sides); regular pyramid (3 to 10 sides). For each geometrical object, certain parameters can be interactively adjusted, such as: height and length of sides, inclination of sides, number of sides, etc. Each object can be gradually and smoothly opened or closed from its basic net to a geometrical object. Each adjustment of parameters is interactive and seen immediately - animated. Each object can be freely rotated in 3D space at 'all times of the process'. Additionally, each object can be zoomed-in, or zoomed-out, at any scale. 3D animation executes at high speed - in real time, even on slower machines.

Data Pilot is specially created to expand data analysis options available in Microsoft Excel with nonparametric statistical methods. The statistical methods used in the application provides the most relevant results even with small numbers of samples (3 or more observations), without any assumptions on distribution of the original sample. This is especially important when analyzing biological information or when doing expensive or difficult to replicate experiments. The tight integration with Microsoft Excel allows users take advantage of the full potential of the program for entering data and creating reports. Data Pilot works with Excel 97, 2000, XP and, most likely, the future versions of Excel.

MIC is an ideal alternative calculator for those working with individual numeracy needs.

MIC uses the same inverted keypad as the mobile ?phone and most other common numeric pads such as ATMs, telephones and remote controls.
MIC provides audio feedback when keys are pressed and differentiates between numeric, operator and function key presses.
MIC displays the entire sum all through the calculation.
MIC uses the modern oblique (/) for the division rather than the older the same as mobiles and spreadsheets.
MIC forces premeditation when carrying out calculations by asking for which operators to display, mobiles do the same by having only one operator key or menu from which the operator is chosen.
MIC offers different levels of precision; remainders which are commonly used with basic skills students; two decimal places for use in monetary situations and six decimal places for metric work, which is sufficient to shift through two major metric units e.g. from mm to m to km.
The cancel button does not obliterate the entire sum, but backs up by one stage with each press.

The Prime Number Spiral (a.k.a. the Ulam Spiral) is constructed as follows: Consider a rectangular grid. We start with the central point and arrange the positive integers in a spiral fashion (anticlockwise). The prime numbers are then marked. There is a tendency for the prime numbers to occur on diagonal lines, however far out into the spiral one goes. This is software is for exploring the Prime Number Spiral. It also (a) allows coloring of the prime numbers in various ways, (b) displays a random arrangement to compare with the primes and (c) shows how square and triangular numbers are located on the spiral.
