I read this article recently which mentions one explanation for "hauntings":

http://www.cracked.com/article_18828_the-creepy-scientific-explanation-behind-ghost-sightings.html

So, one thing to check for would be infrasound. If you find it and can identify the source, you may be able to put a stop to the "hauntings".

He shows how he straightened a picture he took and also mentions the SIFT algorithm which is disabled by default because of software patents. He says:

Your editor, being a daring sort of person, decided that he wanted to find out just what sort of functionality is being denied to hugin users by the oppressive US software patent regime. As it happens, Fedora users can get around patent-based repression by installing the autopano-sift-C package from the rpmfusion repository and tweaking the program preferences to use the real autopano tool. The difference is striking: with autopano-sift-C installed, the program proceeds immediately from image selection to a preview window; the whole "control points" and "optimization" process just sort of goes away. This package does a great job of finding control points, at least on your editor's sample image set.

Yes, because more people can copy him and up the sample size. If enough people do this ( also switching hands, say cracking their right hand and not their left, and also noting left or right handedness ) then you know the results are valid barring any association between liklihood of doing this and assymetric arthritis. Possibly there is a gene that causes both OCD and arthritis.

No, no, that's not double-blind! You have to have someone cracking (or not) your knuckles without you knowing it and also without them knowing whose knuckles are being cracked.
