Rotating Lights is the second installation of the series Noise / Light / Seoul from the artist Stefan Tiefengraber. A kinetic light installation consisting of five, for Korea very typical, fluorescent lamps that can be found in almost everywhere Korea but are slowly starting to disappear. The artist connects these lamps to a custom-made rotating system. Driven by a motor, the lamps start very slowly, the rotating continually speeds up to the maximum rate. After reaching this climax the power turns off—the light goes out and slowly stops spinning. The spectator is left in the dark and now silent space until the lights turn on and start moving again.

These same techniques to produce an experience for the spectators can also be found in the two related works, 징 noise #1 and ppang / 빵, which are also part of the series Noise / Light / Seoul, which the artist created during his stays in Seoul / Korea in 2015 and 2016.

Fog Pixel is an interactive installation that can emit a stream of fog in the rectangular shape of pixel. It was initially designed as a new type of stage expression platform. The artists explored the form and movement of fog to design a unique participatory aesthetic expression through embodied interaction. Using fog as a medium for interactive design, Fog Pixel introduces a method for controlling the fog stream shape, direction and wind velocity, to go along with light and sound. Fog Pixel aims to pave the way for a new type of interactive design.

Lightstorm—two meters high, three meters in diameter, and spinning at 35 kph—is an oversized, rotating tube with LED strips embedded all around the outside. While the cylinder is in motion, the installation visitors’ visual faculties interpret the rapidly blinking LEDs as a drawing in midair. Impressions of pulsating images in space occur on the retina.

The artists mean *Lightstorm* to symbolize the individual amid the maelstrom of big-city life. The 21st-century cityscape is characterized by the proliferation of light sources. The pervasive illumination engulfs people; it suffuses them and their lives; its pulses impart the beat to their personal rhythm. The individual is trapped within a tornado of sensory overload and has to go with the rhythm of the city lights to avoid drowning in them.

We present a method of rendering aerial and volumetric graphics using femtosecond lasers. A high-intensity laser excites physical matter to emit light at an arbitrary 3D position. Popular applications can then be explored especially since plasma induced by a femtosecond laser is safer than that generated by a nanosecond laser. There are two methods of rendering graphics with a femtosecond laser in air: producing holograms using spatial light modulation technology, and scanning a laser beam using a galvano mirror. The holograms and workspace of the system proposed here occupy a volume of up to one cubic centimeter; however, this size is scalable depending on the optical devices and their setup.
