Icon proposed by Kevin Kubasik

It's OK for me, just remove the wire (see current input-keyboard and input-mouse) and eventually fix stuff like pixel perfect and border sizes.
It will be on svn in a week or two

Vinicious, could you please pick up the icon attached to this bug[1], remove the wire, fix pixel perfect/alignmet and in case "merge" with your one? 

As you can see the basic idea is the same, just this one seems "wider". maybe due to the different balancing betten white areas and black areas.

updated input-gaming propose

Luca, I tried to make it squared, but without the wire it just don't look like a gaming input (maybe an strange domino :P). So, I made some changes in my original propose to fit with Kevin ideas, keeping it look like a gaming input.

This icon is in the HighContrast theme in gnome-themes-standard.
