[Interest] Run Console and windows screen

[Daniel Mota]

Thanks again Frank

I think a picture worth a thousand words...

That's what I am trying to do...

Just remarking some points:

1) I am running under windows, not Linux
2) My focus is on the screen, I have the algorithm
3) It is not a homework... is a self learning effort, I am a researcher


Could you gimme some directions?

once again, thanks a lot!

Best regards

Daniel
