The icons can be found in the main theme directory of GNOME, I just looked at every theme directory and picked the best icons available.
Everything I download or create goes into the @INBOX-folder (I used to put everything on the desktop and it was really, reaaaally messy).
When I process the stuff or download something for printing, it goes into @PRINT.
If I create a new document or write a new blog post using JDarkRoom, I will put it into @SOMETIME for later processing. This is where I store ideas and drafts. It's not just a "defer" folder, it's the incubation folder. I use a paper-based organizer, therefore I keep most of my stuff written on plain ol' paper.
