This is a real time test (20 fps) of particle fluid in Blender, the meshing has been made with metaballs. Not BGE, this is for display the variace shadows, enjoy. ( i7CPU, 6 cores, 12 threads)
Very interesting! I loved the shaking at 0:34 
What is the technique for meshing particles with metaballs?
Loving the soundtrack caesar, can I ask where you get your music sources from 
Thanks!! yeah this is a particle system with metaball object linked.
Hahaha, thanks! this is a available free music of youtube soundbank 
No, sorry, the metaball don’t support textures , but with the particle sistems you can do very intesting changes.
