Is there need for me to continue? I haven't bottomed out on Google yet ;~D
That's entirely OK...
Heh...somehow they remind me of that ghost gif that went around awhile back...where you were supposed to look for a ghost in a photograph, and then just when you thought you had it spotted in a corner, a person all in white would pop up and run through - make you jump!
That thing got me bad first time through.
