This is really cool. With a newborn in the home I've been really thinking about projects like this recently. When you have a newborn things are so busy and hectic that it's easy to get overloaded and for things to slip through the cracks so I've been really wishing I had a dashboard like this somewhere to remind me that we need to take the dogs out or show how long it's been since the baby last ate or whatnot.
You have a newborn, and you think spending time installing and maintaining something that displays the calendar around the house is a good use of time?
From what I can tell, the author (of the submission)* can afford being a multimillionaire buying thousand dollar displays and moving into extremely expensive detached housing, so his efforts don't apply to us breeder peon.
That being said, I see a lot of COTS products that fill this niche but all have privacy issues sadly.
