Does anyone know (or is there) an online moodboard or interactive whiteboard online? Where you can jot your ideas/planning down. I would use a simple whiteboard, but because I’m on a comp most of the time, makes sense just to do it online. Save paper, send to others etc.
Paint should do it... There was a time that I did it on the DS as well. Maybe its worth trying to get you hands on the interactive smart board software used by schools... Like here
Take notes in a World of Sand clone. Write them in Concrete, fill them with gasoline and then burn them away with fire when you're done. http://chir.ag/stuff/sand/
Backpackit has a Writeboard function you can share with others. It's been pretty handy for me. http://www.backpackit.com/tour.php#writeboards
