Meet David. Tim Lord ran into him at the 2014 Maker Faire Bay Area. He didn't have a display, and he wasn't obviously trying to sell anything or promote a Kickstarter campaign. He was just walking around with a panel full of LEDs that he wears as a backpack while riding his bike, which beats the heck out of regular bike taillights, even the blinky flashy ones a lot of us have these days. So good on you, David. This is your three minutes of Slashdot fame -- and please note, people, that you can now fast-forward through any preroll ads longer than 30 seconds, so you won't get bombed with multi-minute ads to watch a three minute Slashdot video.
