For every cell in the grid draw a stickfigure with a random color. A stickfigure is a glyph based visualization technique to visualize any kind of data. A circle is segmented in three parts, each 120°. One part for each value of the rgb color. Then a line is drawn visualizing the value. 0 - 255 mapped to 0 - 120°. I made the strokeWeight higher and colored all lines by the color it represents.
