A new company based in Tel Aviv, ARShow, has developed a low cost way to use mobile AR technology to augment live theater, concerts, sporting and special events, allowing hundreds of local participants to share precisely anchored images and special effects combined in real time with live performances. I sat down with co-founder and CEO Sasha Kreindlin last month on his swing through New York, where he showed me how the company had augmented The Gesher Theater production of Gulliver.
