Wonderfull work by California based studio Motion Theory. Check out their work for HP, they even put up their sketches, what i like most.
Also a must see – REM’s Animal video:
An eclipse enables a man (played by R.E.M.’s Michael Stipe) to see the invisible forces of life – emotion, connection, humanity – in the form of visible energy. While the eclipse holds, everything takes on a different quality – energies arise that resemble living constellations, people appear to be connected by bioluminescent strands, and movement creates patterns of light.
