Sticky notes are tricky. Unlike tape, you can’t spin a gigantic web or sculpt a bike-thieving mega-jellyfish out of it. Stop-motion aside, you have to stick to the classics, like giant murals. There’s one at Grand Central Terminal’s Venderbilt Hall right now. It took a record 112,640 Post-it Super Sticky Notes and a month to make. Oh, that OCD… I mean, art.
