Bike Speeding -Quick and Slick

Marking lines on roads are brilliant to ride a bike on. There's less friction between the tire and the ground. This makes higher speeds possible.

On the other hand braking is much more difficult, though. Tires are more likely to slip on the slick marking lines..

enjoy subtleness

sightune: I did some experiments with public displays that show ads in phone booths. simply adding a layer of printed translucent paper! this diffuses the ads and provides back lighting for the new layer of static content on the paper.

Short Bio Johann Gielen

Johann Gielen is a lighting designer and artist. He received his Dipl.-Ing. from HafenCity Universität Hamburg in Urban Planning specialising in natural light art for public spaces. He studied Architectural Lighting Design at KTH Stockholm and Applied Lighting Technology at TU Ilmenau.
Johann Gielen currently works as an independent lighting designer. He previously worked as lighting design lead at Ulrike Brandi Licht. He also headed the lighting design of Sharp LED Lighting Europe and worked for WES Landscape Architects. In his projects he collaborates with architects, designers, artists, media architects and electrical engineers.
Besides well-crafted lighting design his interests lie in subtle lighting effects. All technological means capable of transforming the visual appearance of an object are appealing to him. This interest lead him to become a theorist in the field of Media Architecture writing about ways to create visual media without artificial light sources.
In interdisciplinary collaborations he explores the role and functions of future digital devices in urban environments. He is searching for unusual ways of expression that emphasise the importance of truly public spaces for open societies.
His project Pixel Sonne gained recognition for its unique approach celebrating natural light and its ephemerality. Sunlight is slightly tamed by digital means yet always sustains its irrepressible nature. It has been shown at conferences like Media Architecture Biennale and the International Symposium on Pervasive Displays.
