I found this on the internet debunking one shadow figure that appeared during the Gibbons home investigation. very nice catch I have to say, his findings seem to be pretty concrete. For those who don't remember, this was Ghost Hunters Season 3, Episode 15 where Steve Gonzales believed he caught a shadow out of place.
To set it up:

I thought this was an interesting find AND (EDIT) Grant Wilson had posted about this up on his blog that SciFi still chose to show it on the airing.
