Some interesting things I found on April 25th, 2008:
# KlangStufen – „KlangStufen“ is an experiment to show, how much information you can get from the sound of a city. You can experience the urban space auditivly by mounting the different height levels of a city, which would not be possible in the real space at all. You should concentrate completely on the sounds, the visual remains in the background.

A stair makes the different height levels conceivable to the user. The single steps correspond to the different height levels. So we can use the existing architecture to experience the urban space and to get information about it. The user selects his point of view in the city on a map projected on the wall. Now from this point you move along the y-axis upwards or downwards, depending on which step one is standing.

# Kids Be Gone – Mosquito Device – Are gatherings of teenagers and young adults affecting your business and your profits?
The Mosquito ultrasonic teenage deterrent is the solution to the eternal problem of unwanted gatherings of youths and teenagers in shopping malls and around shops.
# Tristram Cary, Tape Music Pioneer, VCS3 Designer, Composer, Dies – Tristram is credited by some as the father of tape music, originating tape music techniques in World War II. He’s notorious to the general public and sci fi fans as the composer of the music for the Daleks in Doctor Who.
# Puzzlemation – A Dynamic Tiled Display – Puzzlemation divides the digital display into pixels you're free to pick up and re-arrange. It can be used to create things as diverse as modular animated signs, to a uniquely challenging dynamic puzzle.
