The Raspberry Pi. It’s a small computer. It won’t fit in an Altoids tin, but it’s almost the right size.
It’s able to do a lot of the things your normal desktop can do.
You can hook up a monitor to it and run a Linux operating system off it. I use a little keyboard through Bluetooth. You could plug in a corded keyboard and a mouse.
It has two USB ports, an Ethernet port. This is a regular headphone jack. The operating system and programs are stored on this SD card.

Transparent, flexible speaker runs on ions

A research team at Harvard has created a remarkable proof of concept device: a thin, transparent speaker powered by ions instead of electricity. Such "ionic devices" could lead to artificial muscles, telescopic contact lenses, and more.
A thicker, stronger ionic device could replace a damaged muscle. A thinner, smaller one could be a contact lens that adjusts for distance or eye trouble. Another could be wrapped around a heart, ready to make up for weak or missed beats.
