Project description from the site:

A laser harp reimagined as a controller for an interactive audiovisual experience.

An installation that merges a futuristic musical instrument with a videogame.
Distract the beams and hit geometric objects to invoke hypnotizing chain reactions of light and sound, or just admire the experience of literally touching photons.
With “Klanglichter” you can now experience what you dreamt of in the 80s…

Made with Unity, Arduino and LOVE in the Cologne Game Lab by Tobias Kreter and Onat Hekimoglu

How it works,

Using hands to interrupt the laser light from laser sensors, which triggers the visual and sound effects built in Unity.

Why I like it:

Because it explores the possibility of combining arduino with other source of platform, in this case Unity, which provides me much wider possibility and imagination in terms of the application of Arduino in projects. This also provides me with inspirations of how to build projects into a larger scales without wires and sensors heavily involved and displayed. Making a good or a smart use of one type of sensor, then you are good to go.
