Is there a gray scale script?

[enlightened_death]

I was wondering if there was a script out that allows the user to create a gray scale scene, as if for a memory or something? Maybe not quite a full out gray scale, but tone the colors dull. If so, could some one point me in the right direction? If not, could somebody please help me? Thanks in advance. :grin:

Firstly, you've posted this in the wrong section, and secondly I believe what you want can be done with the tint screen command.

Yep, tint screen and the fourth value is saturation.
