PRAYDIO is a combination of a decorative, golden plastic crucifix found in a one Euro shop and a CB-radio. When someone approaches the installation, channel one of the radio opens for ethereal communication. Anyone with a CB-radio within the broadcasting range can reply the prayers, providing instant answers and guidance.

Galactic Dimension is a supersized pinball machine which I’ve built for Phæno – an amazing science center in the German city of Wolfsburg. The pinball was built on a steep ramp in the exhibition hall and has a gigantic playfield, which measures 3×6 meters in total. Styled with UFO’s and other cosmic references, the pinball fits perfectly into the futuristic building designed by the star architect Zaha Hadid.

As a science center should stimulate creativity and inventiveness, I repurposed everyday items like hair dryers and office fans for the playfield elements, giving the visitors the idea that they could also build such a contraption at home. The result is a fully playable machine, operated via a control desk where the score is displayed on a jumbo calculator. Needless to say – hunting the high score is galactic fun! Watch the video above to see the machine in action!

Here’s a video of the “Pneumatic Sponge Ball Accelerator”, installed at the Tschumi Pavilion in Groningen / The Netherlands. The apparatus contains 1000 black sponge balls, which are sucked through 150m of transparent pneumatic tubes with the power of a regular household vacuum cleaner. The balls travel with a speed of about 4m/s. Visitors can operate the machine with a touch sensor mounted on the pavilion’s front glass: They can change the direction of the airflow and watch the balls speed up, slow down and reverse.
