Filter > Render > Clouds (Dark blue as foreground, black as back)
Filter > Distort > Twirl (Forgot what settings)
Filter > Sketch > Chrome (All sliders as far as possible to right)
Image > Adjustments > Color Balance (muck around with blues)
If that doesn't work:
Filter > Render > Clouds (Dark blue as foreground, black as back)
Filter > Distort > Twirl (Forgot what settings)
Filter > Artistic > Plastic Wrap
Filter > Distort > Twirl (same settings as last time)
Filter > Sketch > Chrome (All sliders as far as possible to right)
Image > Adjustments > Color Balance (muck around with blues)
I think thats how I made it.
