Ah, I see. Oh well. Great work and keep it up!
Edit: Second thought, I am rather interested in how you made the symbols too.
Btw...backgrounds are simply some brushes and filters.
About the symbols...i made the first symbols by selecting the single pieces of each and merging them using layers. Then using half background form one and half from the other.
Now i'm trying creating the forms, so i have more freedom, and using the "make your own" file.
