Here is a real time video of the square when the clock starts at 10:00AM, I zoom in so you can sort of see the pixels :

Contest notes:

I am very much out of time to polish this up, but it was still fun to work on. I hope I have the energy to continue throughout the coming weeks and post a more polished project :)

Would the judges perhaps consider changing future contests to have two deadlines to help with the procrastinators amongst us? The first one for "get something in hackaday.io" where you have to submit something to be considered for judging. But then a second "work stop" deadline, where you can't add anything else. This would perhaps help or encourage the use of .io's update feed :)
