By letting people reach into thin air and create huge changes from tiny actions, interactive art exhibits can break down the barriers between art and audience. Last week, we looked at two recent art installations to use the Leap Motion Controller to challenge how we interact with nature and technology. Here are four more exhibits that made waves in 2013:

A Surreal World of Alien Shapes

One of the earliest art installations to use Leap Motion technology was Untitled°, created in June by NATURE graphique for Stereolux, a French digital arts and culture space. The exhibit allowed viewers to immerse themselves within a monochromatic 3D scene and explore the landscape with simple hand movements.

Human Actions and Natural Consequences

Vermont-based artist Craig Winslow’s Growth is a 3D-projection mapping experience that lets you manipulate digital vines, branches, and beams of light cropping up against a stark blue sky. Soothing movements create beautiful scenes, while aggressive swipes summon darkness – telling the story of humanity’s relationship with nature. Read more »

What if Social Media was Art?

Forge Collective’s Toronto installation Connexion Point allowed complete strangers to make connections and create a dynamic digital community through Leap Motion interaction. After contributing personal stories into a colorful world of geometric shapes, visitors were able to create, capture, and collect random collections of stories. Read more »

Welcome to Our Universe, Have a Seat

Created for production company B-Reel’s London office, Star Canvas is an interactive guestbook in the form of a giant projected star chart. It uses real star data and classical illustrations, some creative interpretations based on B-Reel’s current film projects, and a sound engine that turned the whole thing into a giant synthesizer. Visitors were able to draw and name their own constellations, then set it free as a shooting star.

While it takes a few extra steps to project it onto a building or within an art gallery, you can also create your own art with the Leap Motion Controller. The Airspace Store’s creative tools category includes a variety of artistic tools for everyone to enjoy – from finger painting to clay sculpting.
