Phew, I skipped a day, but I'm caught up at 8 seconds right now. I know it's technically the 5th, but I'm still awake from the 4th. :P
I'm doing FBF too. Mine'll be mostly animation exercises, like I have a bouncing ball, and a man with no arms walking, but I'm finding ways to make it somewhat interesting. I'm not worrying too much about finish, so it isn't taking too long for me.
I think I might just do this as a monthly thing. 2 seconds of practice every day will add up pretty quickly if you do it all year.
