From the Official press release for the Garden of NPIRL Delights:

THE GARDEN OF NPIRL DELIGHTS
Presented by Rezzable Productions and the Not Possible in Real Life Group
A Virtual Art Show that Would Not be Possible in Real Life

(May 15, 2008) (SECOND LIFE) - Rezzable Productions , the largest developer of public spaces in virtual worlds, and Not Possible in Real Life (NPIRL), a working group dedicated to identifying, sharing and showcasing well conceived and realized content creation that would not be possible in Real Life, have joined forces to hold the largest-scale art show of its kind in the metaverse. Taking a page from Hieronymus Bosch, Rezzable and NPIRL have enlisted the participation of over 100 of Second Life®'s artists, architects, builders and coders to construct the NPIRL Garden of our collective dreams, spanning four simulators/islands to illustrate: the Underworld, Earth, and Paradise.

NPIRL's inaugural build festival, sponsored by Rezzable Productions, will open its doors to the public on Friday, May 16th through June 22nd, and hold numerous events, including music (both live and DJs), and tutorials. Musicians interested in performing at the Garden should contact Gweneth Lange. For all other events, please contact Vint Falken.

Rezzable Productions and the Not Possible In Real Life group have joined forces to hold a large-scale two month extravaganza loosely themed around “The Garden of NPIRL Delights.”

This isn't just about building. It's about giving content creators free reign to further discover their creative might *flex!* and the opportunity to shape our virtual world in ways that... yea, you got it, would not be possible in Real Life.

Taking a page from that madman and artist, Hieronymus Bosch, Rezzable and the Not Possible In Real Life Group invite you to help us conceive and construct the NPIRL Garden of our collective dreams, spanning four sims to illustrate: the Underworld, Earth, and Paradise.

This is not about recreating Bosch's Garden. It's about imagining and crafting your own. If you were to journey into heaven or hell, what would this look like, and how might you make this as immersive as possible? Think Dante's "Divine Comedy," but with your own twist. And what are the earthlings doing that might force them into the depths of the underworld or paradise? Don't limit yourself to looking at this from a Biblical sense. Create your interpretation and own it. It could take place in any era: past, present or future. If you like, you can use it to cross-promote a current build, but this must be original work.
