LDR measurement help

[mvader]

I'm using an LDR and when i put my finger over it (complete darkness)
i get this odd "wave like" reading over and over.
you can see that happen and then when i take my finger off, the value starts to climb steadily but with no "wave like"
readings going on.

so my question is what is going on and how do i resolve it?
