NASA’s Starshade

This animation shows the prototype starshade, a giant structure designed to block the glare of stars so that future space telescopes can take pictures of planets.”

(That last GIF is a prototype,’s like we’re using the natural mechanics of flower petals for awesome.)

One day this may be used to take the first picture of another Earth. 




Ring-like wearable device that can read aloud text as you guide it with your finger - video embedded below:

The FingerReader is a wearable device that assists in reading printed text. It is a tool both for visually impaired people that require help with accessing printed text, as well as an aid for language translation. Wearers scan a text line with their finger and receive an audio feedback of the words and a haptic feedback of the layout: start and end of line, new line, and other cues. The FingerReader algorithm knows to detect and give feedback when the user veers away from the baseline of the text, and helps them maintain a straight scanning motion within the line.
