# Create the text layer, white on black:
1. Use a large, blocky font
2. Blur this layer with a gaussian blur so that the details of the text are still recognizable (holes in letters like 'A' shouldn't end up closed). One eighth the point size works well. The stronger the blur, the less readable the final output will be.
# Create the difference clouds layer
1. Set the blending mode for the clouds layer to 'Negation'
2. Render clouds with the scale for the clouds at roughly twice the font size.
3. Repeat it a bunch to get a whispy look
# Use Levels to adjust the clouds laye
