My first take when I saw this was oh no more piles.
I'm sure we would all agree that the temptation to create lots of piles on your desktop is a bad idea but there are some other interesting ideas here.
Sticking things on the walls is pretty sweet. Throwing the 5 next actions you want to do today into a floating grid...maybe with the projects tacked on the walls is pretty cool. Maybe a pile of next actions. I think this has potential. What do you think?
