While playing with the Tendril code, I started to get more and more fascinated by the particle engine that is creating the bubble objects. For this version, I shortened the main tendril lengths, killed off the tendril branches and pulled the bubble emitter back towards the skin of the main tendril (sounds vaguely dirty).
