Adres MAC (ang. MAC address) jest 48-bitowy i zapisywany jest heksadecymalnie (szesnastkowo)...
Do zapisu liczb potrzebne jest szesnaście cyfr. Poza cyframi dziesiętnymi od 0 do 9 używa się pierwszych sześciu liter alfabetu łacińskiego: A, B, C, D, E, F.

kylonik czy mógłbyś opisać dokładniej o co chodzi z tym efektem skryptu? Jak go uruchamiałeś i ogólnie nieco więcej info.
