Nifty little exercise where a group of designers turn a train station staircase into a piano keyboard (a la the classic scene from Big) in order to get people to engage in the healthier behavior of taking the stairs rather than the escalator. THey conclude:
“Fun can obviously change behavior for the better” and the slightly more difficult translation “Add fun changes common behavior”
Nice implementation, if you will, of a vacuum cleaner bag. My last vacuum, which I loved (major power!), had perfectly square bags, with perfectly square cardboard around a perfectly round rubber seal. Even when I tried to remember how I removed the previous bag, it was trial and error getting the new bag in — lots of rips and misalignments. No mistakes possible with my new Miele, though! It has a guide, and matching arrows on the bag and the guide and no need to mess with the seal . . . the guide puts it in place for you.
