Bill Beaty says "The author is making his own version of those 3D advertising signs popular in the late 1980s. (I saw many of these mounted on the walls of corridors at large airports.) They're "lenticular" 3D which uses pinhole optics rather than cylinder lenses." Link.

The discussion surrounding DIY seminar talks by Mimi Ito and Howard Rheingold last week raised some compelling questions about how to imagine a non-dichotomized architecture for media creation and circulation (as Julian Bleeker put it in his comments below). DIY is not simply an obscure hobby of media activists and enthusiast, or a phenomenon that exists exclusively in opposition to mainstream production practices. DIY, we seem to agree, is an ethos that is increasingly seeping into the mainstream. And as John Seely Brown pointed out, assumptions about leisure and entertainment might be in the process of shifting by virtue of new production practices associated with DIY.

Mimi Ito’s talk is entitled "Amateur Cultural Production in the New Networked Age." She is a cultural anthropologist who studies new media use, particularly among young people in Japan and the US. She is currently co-leading a multi-year project on Digital Kids and Informal Learning, with support from the MacArthur Foundation. As part of this project she is conducting case studies of anime fandoms in Japan and the English-speaking online world. She is a Senior Fellow at the Annenberg Center for Communication.
