Happy Pi Day, or Half Tau Day...to mark the day, I've made my biggest spiral yet...and using a formula with Pi, I estimated the total dominos in this spiral to be 10178.75 dominos. I counted the dominos and the estimate was close. 10,059 dominos were actually used.

Extras and full fall down in real time can be seen here:
