Boing Boing tv's Matt West visits Machine Project, where scholars and gladiators have gathered to reconstruct Rome in exactly 24 hours.

Xeni visits the Steampunk Tree House, a 40+-foot-tall interactive sculpture created by a group of artists in Oakland, CA, and assembled for the first time at Burning Man. More than 60 people helped to create it, and in today's episode, you'll hear from project participants Alan Rorie, Nathaniel Taylor, and David Shulman.

Update: Scott Beale has been following this project for a while over at Laughing Squid blog: Link.

Boing Boing tv pal Matt West interviews Danny Scheible, an artist who makes elaborate, luminous, wearable art from masking tape. One of his better known works was an entire city constructed from masking tape and painter's tape, called "Tapigami."

Next, a sneak preview from U2 3D, a stereoscopic 3D movie opening this week in US theaters which showcases the band's use of technology to create immersive experiences for fans in concert. There's a blog for the film here.

Music in this episode: Beef Wellington, from Eighth Dimension Records (Special thanks, Michael Donaldson, Souris Hong-Porretta, and Thor!)

Today on Boing Boing tv, two pieces of nature-themed video art. First, an excerpt from WILDERNESS TROUBLE, produced by Cary Peppermint and Christine Nadir of the ecology, art, and technology collective EcoArtTech:

[This work was] inspired by William Cronon's article, "The Trouble with Wilderness; or, Getting Back to the Wrong Nature," which argues that the concept of wilderness is a historical and cultural construct and relying on it as the basis of environmental ethics fails to imagine new, healthy, and sustainable relationships between humans and the environments they actually inhabit.

Next, CRAB FU, an animated short by I-Wei Huang (crabfu.com). No crustaceans were harmed, we promise.

Editor's note: This BBtv episode is sponsored by Dell's regeneration.org project -- but purely by coincidence, a Dell PDA appears in the opening sequence of "Wilderness Trouble." This is not product placement or advertorial. EcoArtTech produced this film in 2007, and the air date of this excerpt was not planned to coincide with the sponsorship campaign.

Boing Boing Gadgets editor Joel Johnson chats about chiptunes with a number of artists who performed at the most recent installment of the 8-bit music event Blipfest: Paza Rahm (pazarahm.com, from Sweden), Rugar (rugarandi.com, Sweden), Sabrepulse (myspace.com/sabrepulse, Scotland) and Akira, aka 8GB (myspace.com/8gb, Argentina).
