Sometime in the aughts, signs showing future buildings started to loom weirdly large in the landscape; all those shiny condo ads seemed to be an urban feature of their own—especially when the crash left many structures unbuilt. But an ongoing project in New Orleans continues to take the form to its illogical conclusion.

"We decided this was an interesting medium," relates Rob Walker of the Hypothetical Development Organization (which we previously covered here). His fake realtors ask artists to imagine inventive uses for neglected city buildings, and to render these on ad-style signs that will be hung on the buildings themselves. The concepts are, in Walker's words, "blatantly implausible," and this is by design. If an ad for a glossy high-rise is only a pipe dream, their thinking goes, why not have more interesting pipe dreams? The signs produced so far include "Museum of the Self," which is adorned with a massive Facebook "like" thumb; a designated "Loitering Centre" (above), which envisions tasteful malingering in a dilapidated shed on Magazine Street; and the "Velvet Rope Artisan Workshop," whose description defends its premise quite reasonably: "If you need a velvet rope, you want a handmade, custom velvet rope, from a recognized velvet rope artisan."

The artist Candy Chang, who created the door hangers that appeared in GOOD 019,  recently contributed a "Mobile Cornucopia," which plunks a building onto the back of a pickup for extreme produce truck service;  Walker expects six to eight more to be posted by April.
