Bloody awesome mate! 
A flowfield for the particles at the start would've been cool, I'm having some good fun playing with flowfields atm. 
@Kirl, hehe. That would have been good. I didn't get my head around flow-fields in time though

I plan on abusing the hell out of them in my next intro though

Would love to see what you've done with them at some point. They really do make things feel organic and alive.
@C3ltic, thank you
