This eaxample shows the difference between two different HTML rendering methods. First method "Fast RLE" uses RLE compression (by means of colspan attribute of the table cells) on lines only. Second method is "Optimised RLE" - on each step it is trying to find a largest possible square area of the same color and produces a single cell for it by manipulating both colspan and rowspan attributes of the table.
Notation: red hand - seconds, green hand - minutes, blue hand - hours.
