The Sky Norns were under development and being made by Blue_eyed_alley_catz, orfeo, and Speeder. They are a type of norn that are somewhat like clouds and change sprites depending on mood, thundering when angry or frightened, and raining when sad. Speeder thought of the idea on Albia 2000 while Blue_eyed_alley_catz did the sprites and Orfeo was doing the genome. A while ago, both Orfeo and Speeder disappeared from the project while blue_eyed_alley_catz finished the sprites. The sprites were released for free use on Friday the 13th, 2007. You can download the sprites here.
