About Knot-That-Easy

=====================

- Author: Jorge A. Torres 

- URL: http://jorgeatorres.github.io/knot-that-easy

- Source code: http://github.com/jorgeatorres/knot-that-easy

Knot-That-Easy is a program useful for getting information about mathematical knots (http://mathworld.wolfram.com/Knot.html) by being able to actually "draw" a regular diagram of the knot inside the application.

Features

========

- It doesn't force you to use some sort of complicated knot codification system: you can enter a regular diagram of the knot using the mouse by drawing lines, creating over and under crossings, etc.

- It looks pretty nice compared to what is available right now on Linux and other platforms.

- Knot-That-Easy is written in Python using PyGTK+ for the UI so it should work across supported GTK+ platforms (Windows, OS X, Linux).

- Knot-That-Easy can determine the following data about a regular diagram of a knot:

    - # of crossings and arcs

    - alternance of the diagram

    - writhe

    - Gauss and Dowker codes

    - the Wirtinger presentation of the fundamental group of the knot

    - 3-colorability

Requirements

=============

- Python

- PyGTK+ (including Glade support)
