All that is needed is the C# code to redimension/resize the structure as shown in the following video:

click on the link to watch the video and make the same screen impression that can be seen on the board.

I already have the code of the X rectangular structure, is written here below, it just needs to resize animation like in the video

using System;

class Program { static void Main() { for(int i = 0;i<17;i++){ for(int j = 0;j<20;j++){ if(i == 0 || i == 16 || j == 0 || j == 19) Console.Write("X"); else Console.Write(" "); } Console.WriteLine(""); } Console.ReadKey(); } }
