Tidbyt
A month ago, I bought a Tidbyt. It's a fun, beautiful little lo-fi display screen for displaying micro content. The thing is really well designed and looks great on the shelf. I have six apps in rotation, so there's also a nice variety in what's displayed. A 3-day weather forecast. A photo of Lisa and I. A pretty Day/Night globe view. A fuzzy clock ("Twenty-Five Till One"), a day/month/year progress thing, and an MTA train tracker for the F line. There are a ton more apps, but these are the ones working for me at the moment. Being a relatively new product, I'm sure more great apps will be added as time goes on. I'd love to design and build one myself if I can think of something new to make.
On mornings when I go into the midtown office, I check the F train time to see if there were any delays. Yesterday, there was! Imagine that. Signal malfunctions on the line meant the train ended up stuck on the track for a long while. So I knew to walk to Jay Street to catch the A/C instead. It's a silly little techy box, but I love it. Highly recommend buying one for yourself or someone else.
