The Leap Motion team was impressed by how quickly Hack Reactor students took to these tools:
"The Hack Reactor students had a great time and picked up the new technology surprisingly quickly. The room lit up when they first unboxed the new devices and played around with some of the apps from Airspace. Dave then demoed how easy it [is[ to code for the device. Three.js and Leap.js can be combined in infinite ways – from drawing with your finger in 3D space to controlling any virtual object’s direction based on hand position."
