The site begins with a blank etch-a-sketch board. It contains an N by N grid of boxes that are initially gray. N, the resolution of the grid, is determined by the sliding bar at the top of the board. As the user hovers over a grid box, it is recolored to black. All grid boxes are reset to the initial gray color when the 'Reset!' button is pressed.

The board is cleared when the user changes the thickness of their drawing instrument; instead, the application could be written such that the black-colored grid elements are interpolated depending on the resolution change. The board styling and color palette could be improved to be more visually appealing.
