A team of Google engineers in Japan created a keyboard in the shape of a keycap that can be worn as a hat. The device contains a 6-axis inertial sensor that can read the hat’s positioning.

It wasn’t the acting, it was the hats. There are a handful of hat stores in the area. At the Charleston Hat Shop, I heard a man ask if they sold engineer hats. Those were on back order, by the way.

But there are some strings attached. When finished, these hats are delivered to organizations that help the homeless. The 88-year-old Underwood helped start the group now known as the Mad Hatters.
