I guess if there's a theme to this week's videos, it would be "art".
The first is of a new technology (light-emitting textiles) to make clothes that contain colorful moving images.
The second shows a type of "paintbrush" that samples colors and patterns from objects and uses them to "paint".
This last one is an "artist at work", creating a short movie. And I did have to watch it twice to see all that was happening in the video because I got distracted by the naked guy in it.
