For my hobby project I would like to implement spooky fog. In the concept I have just static texture, so the job would be bringing the fog to life. Adding fog like movement, overall making it look good. It would probably require both good knowledge of Materials and Particle system.
If both parties are happy, there would be definitely more work to follow.
