Last Day #HTB2013 of Hot Ephemerates

Today is the last day of my Hot Ephemerates at Hack The Barbican London residency #HTB2013. While I couldn't attend personally, the project gave me some insight and inspiration for new code work. Hey, launching an unlimited number of code sculptures in the Barbican is exposure!

Below are two views of No. 1, one of the six sculptures that visitors to the public hallway near the Curve exit have discovered. I modified my iPad settings so as I work in Greenport NY, the iPad thinks it's located in London.


The neighbor's house across the intersection in Greenport shows a corner of sculpture No. 1.


To the right of the sculpture is the top of sculpture No. 2.

I'm paying for comments and documentation images by visitors taking screenshots of the sculptures.

In the spirit of hacking and sharing, I'm publishing the code for Hot Ephemerates here. The other five sculptures in this location use the same code with different variable names so all the sculptural elements will show at the same time.

Seventy-three separate elements (35 .zip model files, 35 .jpg images, 3 .mov movies) were used to build these Hot Ephemerates. I wrote 533 lines of code which includes commenting. My tool set are SketchUp Pro to build the models, Adobe Photoshop CS4 to edit the images, Final Cut Pro v.7 to edit the movies, Junaio to provide AR specifications and free browser, SubEthaEdit to edit the PHP files, and Fetch to load the files to the internet server. 1and1 is the hosting company.

Screen shot today from iPad in Greenport NY of two sculptures from Flaneur Babican - Hot Ephemerates. This is hack, I put the local latitude and longitude coordinates of the #HTB2013 Barbican in London into my iPad to relocate the sculptures in the USA.

Flaneur Barbican - Hot Ephemerates moves to London

"Flaneur Barbican - Hot Ephemerates" is public and live at the Hack The Barbican. Effectively, this means the installation is in technical trials until its opening on Monday, August 26th. More details available at installation page where visitors can download this Junaio channel by QR code method.


The installation begins in the Curve Exit Gallery 5B arcs around the crescent of the venue to give a pleasing perspective to the 3D sculptural elements. Additionally, three Doric columns are aligned along Beech Street. Each 3D column launches a different short video when the visitor touches the object on the screen.

I renamed the AR channel "Flaneur Barbican - Hot Ephemerates" - - my partner Terese Svoboda proposed the catchy Hot Ephemerates moniker. Here's the channel description,
"You, a wanderer at Hack The Barbican discover Hot Ephemerates automatically rendered 3D code sculpture.
- Walk into any sculpture.
- Share a screenshot with icon found on lower left hand corner of screen.
- Touch a street side column to see a short video."


For the curious in today's development, note in this screen grab of taken from the Junaio iPad-view browser interface, I was launching the channel from my studio in Greenport NY see the blue dot within the blue circle on the left. I will continue to tweak the installation in London until Sunday. Zooming in on the venue by the two finger iPad method produced the image at the top of this posting.

Progress 13.08.10 Flaneur Barbican ARt

On a Greenport NY intersection I am experimenting with another direction to create 3D objects for the Flanuer Barbican installation at Hack The Barbican.


Within the red cylinder a blue transparent rod appears. In the background beyond the red cylinder a DNA taro leaf spiral appears. In the upper right hand corner of the screen/image three objects are shown captured in this view.



From a position outside the perimeter of the red cylinder the blue cylinder does not appear. Apparently[pun], a transparent 3D object can not be seen within another transparent 3D object. An unrelated second large blue cylinder appears alongside the red cylinder.

Check out the nine photos Flickr in order with captions beginning "c1-test" for some how-to on how I made the 3D object.

Here is the code of the two object files exported by SketchUp Pro.

"Flaneur Barbican" in Hack the Barbican

Location: Curve Exit, Barbican, London UK
Dates: August 26-31, 2013

"Flaneur Barbican" is a site specific augmented reality installation for the Hack the Barbican residency, August 2013. Fortuitously I just ended the 150th Residency at the Atlantic Center for the Arts (ACA) leaving with a greater clarity of this installation. In part, I plan to put a room within a room by AR method. The interior of Roberson Dance Studio of ACA will be placed into the Curve Exit interior space of the Barbican.



Using their smart phone or tablet, each visitor to the "Flaneur Barbican" AR installation will look for floating sleeping faces. Touching a face wakes a short performance video.

> > > TOUCH THE CAMEO ABOVE < < <

I have a working prototype now. I plan to share a work-in-progress link to the AR channel soon. The installation AR is coded for the Junaio browser, a FREE download found in Android and Apple iPad/iPhone stores, use "junaio" in your search string. The installation code will become publicly available.

I would like to include more performances from the Barbican locale or wherever. The current AR performers are either movers (dancers) or musicians of the 150th Residency. Interested in adding your's? Please email/DropBox me your performance video, .mov, 10 to 30 seconds; your performance video length, thus file size, is limited by the download bandwidth to the mobile device. It would be really awesome if a submitter(s) made their video in or around the Barbican so later the installation visitor will try to discover the performance location and possibly create her own own mobile phone performance video response. I will review all videos submissions and the engaging ones will get my further formatting and preparation for the AR installation. HINT: I prefer steady video shots using a tripod - - it's only ~15 seconds! IMHO: The zoom lens is only useful to frame a shot, then leave the zoom untouched. OKAY: Challenge me and break the earlier directives. SAMPLE: To give you a taste of what I am looking for touch the floating AR face above. TECHNICAL: The linked movie was shot in the Roberson Dance Studio using a Flip camera and finished with FCP + a QuickTime conversion for AR mobile browser display.
