INTERFACES: There are some great icons of game systems (including the fabulous GameCube and those other systems I care nothing about) at MaxThemes. The artist is Max Rudberg.
Icons are available for Windows and Mac, but Mac users can also find some other cool icons and system tweaks for their system at MaxThemes. Also, note that the mac versions won't have those jagged lines; those are unique for us old-skool (a.k.a. lame) .ico users.
