Here's a short animated film by Jeff Chiba Stearns that I liked. 2,300 sticky notes were used.
I've only recently started composing to-do lists, realizing that there was a lot of little stuff at work I would not remember to do. My lists are super boring and full of lame. I feel like I should spruce my to-do lists up with megalomaniacal ambitions and whimsy. Maybe I should remember how to spell megalomaniacal first without checking the dictionary. That is number one on the list.
