Niels is a self-professed browser geek. Back in the day, he created HTML5test, and loves the web platform and standards. He is currently obsessed with connecting the web to physical devices, which sometimes leads to unexpected results, such as a CSS-powered flamethrower. Luckily, not everything he does is that dangerous, but he did manage to blow up an old 1980’s oscilloscope during an experiment with WebAudio. For his day job, he is CTO of Salonhub and creates web applications for hair salons.
Beyond Tellerrand @btconf is happening again on April 27 and 28th in Dusseldorf. And a little birdie told me a certain someone is going to show off their BadClock™ and much more. Lasers. Yes. Lasers and smoke and more...
