As long as we keep burning fossil fuels, we'll have to deal with air pollution. Air Pollution Ink uses it to create something worthwhile. By capturing pollution at the source — a car's exhaust pipe — students at the MIT Media Lab can turn it into carbon black ink. Every 45 minutes of driving renders 1 ml of liquid ink, which is then used to fill the 2mm, 15mm, 30mm, and 50mm markers, as well as the 150ml containers of screen printing ink.
Presentations are nerve-wracking affairs, whether you're an inexperienced speaker or a seasoned pro. The Spotlight Presentation Remote helps give you more control over the proceedings than ever before. It syncs up wirelessly and uses a companion app to let you change the pointer mode, set timed vibration alerts to nudge you along, and activate functions like gesture-controlled volume control. It also lets you magnify points on your slide, highlighting details while keeping the audience engaged, and the cursor control lets you do things like play videos and open links without going anywhere near a mouse.
