Whiteboards and calendars with lists of stuff I need to do.
Cork-boards of random prints/pictures and fan art from my comics.
Scanner. Printer.
Drawing tablet, to do the drawing of the comic pages on.
Monitor 1 for reference stuff, either with script or images, whatever I need at the moment.
Monitor 2 for music playlist, chats, hangouts, netflix... you know... so it doesn't get the way with work.
(my brother gives me his old stuff when he updates his computers)
And drawers and drawers of traditional art supplies that I don't use anymore because arthritis (all drawers not in picture)
