I was inspired by the thought that sometimes people perceive things in clouds that seem to be objects from out of their dreams.
So I started modeling the unicorn first, rigged it and tested some fluid simulations over its movement (I uploaded some of these tests on my facebook-page). While I was working on the unicorn I got the idea of the mermaid. The idea of the phoenix was for a certain part based on wonderwalls, for an other part it was based upon a feeling that the fire simulation and the trace of its flight would do a very beautiful job in Krakatoa. The blossom at the beginning was based on an idea I had a long time before when I didn't have the possibilities to realize it. Maybe I'll come back to this idea in some later projects that will have other storylines...
