Tested alternating direction of number updates, and it looks pretty neat. Will have to rethink the "animations" and the font, but as the layout seem to be in a changing state I reckon I should wait until it's finished
Added a second row to include date and temperature as there were some "spare" MAX7221 laying around.
Been pondering about the case. Tested an old IKEA frame and it's a perfect fit for 4x3 modules, all thou you lose the left, right column and top and bottom row.
Going to try to modify it for 4x2 instead, saving the bottom and top row.
