Love the idea. Would be more useful if it could fill the whole page dynamically. So I could put it up on display on an old phone, tablet or tv screen. Something which put me off was, that it does not update often enough. It took a while for the numbers to change, so I thought it's static. And even when it does, it flips digits which were not effected. I would like it better if only the effected digits change.
