Which type(s) of noise did you use across your submission?
each composer used different noise techniques in their noise tracks! i can't speak to them all but i recorded random noise around me and distorted it with various digital effects. there should be a variety of different audio noise styles for everyone to listen to.
also visual noise (snow) was employed in the accompanying art.

Did you use the optional theme of ANGELS & FATES? If so, how?
yes! i am not sure if every composer used this theme but some of the track names reference angels, plus i used noise from the graveyard where i took photos of angel statues.
