Kinda sorta... I've got an MP3 recording of waves lapping that I play via my MP3 player hooked into a portable iPod/MP3 speaker set, so I figure that's close enough. Wife's might institutionalize me if I wire up some speakers and pipe in SH4 into the bedroom.
Aw, heck... I gotta make a run to the store. If the wife was gonna institutionalize me, she'd have done so long before now, right?
