Hard to tell on the 640 pixel version, but the noise is actually just a window screen.
I tried to put the background just a tiny bit out of the depth of field, to keep it very inviting looking. Hope the window screen didn't mess it up too much.
This made me laugh! I'm going to share it with the youthful gamer in our family! I like the window screen touch, makes it look like the great outdoors may be out of reach from the time spent on games and the like. Nice job.
