Welcome to Etch A Sketch!
        
          - You can draw with three different pens: black, random, or 
          one that starts light grey and every time the pen passes over a cell it turns darker.
- You can also reset the grid (wipe it clean) or reset and choose a different numbers 
          of cells per side.
- Finally, you can toggle between showing all the grid lines and having an outer border and 
          no grid lines.
