@Ab000dy_85: Thank you. :) There is enough space left for improvement. Why not turn this into a forms or WPF application!

well after seen this I actually made the GUI based :/
I was so bored haha, but not as good as yours,, need improvements :D

here is what it looks like,
I just was very bored when I did it, because I wanna learn C#

I love C# and all, but I need to learn alot more,

I find Delegates, and events kinda hard to set up.
I kno how to use them but I cannot create them yet.

yes, my main struggle is when I want another class call back a function in main form,
I have to set up a custom delegate,
I actually havent try to do it yet? but like 2 years ago I remember I was trying hard.
now different story I understand better, but need to try again, especially my project at work I am designing it from scratch through C# starting from sometime this week after I get all parts needed for the High level design done

@StaubRein: be my guest! Use this code as you see fit!
You could also implement a background like this:

class Program
    {
        static void Main(string[] args)
        {
            Console.BackgroundColor = ConsoleColor.Cyan;
            Console.ForegroundColor = ConsoleColor.Black;
            Console.Clear();
            Console.WriteLine("Hello!");
            Console.ReadKey();
        }
    }
