Brockengespenst (Brocken Spectre)

John Muir on the summit of Half Dome in 1875:

"perfectly glorious... A massive cloud of pure pearl luster... was arched across the valley from wall to wall... My shadow, clearly outlined, about half a mile long, lay upon this glorious white surface with startling effect. I walked back and forth, waved my arms and struck all sorts of attitudes, to see every slightest movement enormously exaggerated."

The Wooden Mirror by Daniel Rozin

The Wooden Mirror is an example of interactive design that uses old and new, pixel and physical, technology and craft.  It's like a Sparkletts truck with artificial intelligence.

I've always been fond of Sparkletts trucks.

Typography, Light, and Shadow

I went to a presentation at Art Center College of Art and Design by a graduate student, Jiyeon Song.  The first two images represent her experiential typography design.  Words are cast through angled perforations and form poem stanzas as the sun moves over the sky.  The other pieces are by Fred Eerdekens.
