Creating Splash Texture for Interior Walls

I have decided to create 'splashes' from laser cut pieces that will line the interior of my walls. To do this I have created a texture that I will 'paint' onto my interior walls in sketch-up and then roughly trace over to give me a basis for the splash forms. Below is my process for making this texture, it could also easily be made into water topography as a way of a stylized render. What I like about this technique is that it is so quick and easy:

My first step was rendering random clouds using the filter drop down box. I have rendered this a couple of times to get a good balance of dark and light clouds. 

The next step was using a crystallized pixellation. I have used a cell size of 25 in order to give pixel-late the clouds into proportionate 'clumps'

The last step is using the filter gallery to add accented edges under the brush stroke dialogue box. Using the parameters of:

Edge Width: 1, Edge Brightness: 0 and Smoothness: 15 creates this really nice texture.

 This texture could then be further edited to emphasise certain parts or erase others etc. But I am going to use it as a base to outline splashes on my wall.
