1. A poster covered with classic books that you can "scratch off" (like a scratch ticket) as you read them.
6. A little device you can use to scan the barcodes of running-on-empty items in your kitchen (to create a grocery list).
You can also add to your list with your voice (the device — Hiku — has a microphone) or via an app. Then, when it's time to go shopping, just open up the app on your phone to peruse your list.
