Porter's forces tool

Hello everyone,

Today we are presenting a tool that can be used in the training sessions. It is finishing development, and we are looking for your comments and suggestions.
This tool allows a teacher to organize discussion in topics such as Porter's forces (strategies / threats) so that trainees/students can play with it to develop models of opposing forces. The tool has an arrow in the center. Above and below this arrow, there are several small cylinders, which are used to define the strength of downward forces (threats) and the strength of upward forces (strategies).

How to use it?

Easy! You'll see T-shaped buttons. Clicking on them will pop up an area where you can place text, so that all participants know what a specific force represents. To enter text in this area, you only need to chat after clicking the T, following the instructions provided. For instance, if after clicking the T it says "type /99 text", you can chat:

/99 The threat of substitute products or services

...and this will display "The threat of substitute products or services" in the force column.

At any moment, one can click on the cilinders that compose a force column, and that indicates how strong it is. Filled (painted) cilinders represent the force's strength, empty (transparent) cilinders are ignored. As discussion evolves, simply click them.

The central arrow will tilt down or up, according to the strengths of all downward and upward forces, so you can create models where forces even out (and the arrow is balanced), or where the arrow tilts down (downward forces are stronger than upward forces) or tilts up (upward forces are stronger than downward forces).

Basically, it's an interactive graphic which you can use in discussion and then take a screenshot in the end to illustrate some final text on what was discussed.
