i just came up with the idea of physical digital post-it notes
they are just small e-ink screens with a magnet at the back you update via your computer
this way you can have a physical kanban board with the content from your digital one or issue tracker
but turns out, engineers at microsoft had the idea before
@davidak that looks quite good...
this is it exactly!
