Random mask generator?

[Monkeybrother]

Hi.

Does anyone know if there's a program/technique or PS plugin that can generate completely random black & white textures? The ideal solution would be a program where you can adjust noise, blurriness, x+y pattern, splotchiness and so on, but I have a feeling that that's too much to ask. :)

I always use lots of layers with masks and I have a few favourite random textures that I use a lot, but I want more variety. There are many ways to make semi-random masks by hand, but since I'm making them they are never truly random.

Any tips are appreciated!

Here are two examples (that are probably hand-made, but still):

I use filter forge for this sort of stuff. Node based and works stand alone or as a plugin for photoshop.
