Visitors to the Walker’s Frida Kahlo exhibition have the option of renting a multimedia guide ($6, $5 Walker members). The tour was produced by Antenna Audio whose staff are providing bi-weekly reports on usage. Here’s what we know so far:

  • Take-up rate varies widely depending on attendance with the average being 9%. Thursdays are our big day with typically around 22% (Walker admission is free on Thursday nights). Saturdays are also a big day but the take up ratio (.05%) is diluted by Free First Saturday (FFS) attendance. FFS is the Walker family day; we had 4,800 visitors on November 3rd, a large percentage of which were 12 and under.
  • The numbers show far more non-members purchase the tour versus members (approximately 20:1). However, once members purchase the tour, they’ve come back multiple times, often with friends and family.
  • The 50+ crowd are the folks purchasing the tour. Teens and 20-somethings think they know it all and tend to dismiss it. I wonder how much this demographic might change if the tour was free and/or offered on personal technology.
  • Antenna’s new hardware appears to be holding up to public use. By the end of a 6-hour day, the players can get a bit sluggish but they brought in additional units so they can rotate more frequently.
  • The comments from visitors continue to be overwhelmingly positive. Some of the quotes we’ve gotten:”Fantastic…indispensable for understanding the heavy symbolism of her work.”"…loved additional visuals on touch screen…” \r\n\r\n”…would have been lost without it…”

    “…numbers next to paintings should be larger…” (Sigh. The labels, always the labels.)

    “Excellent to have optional perspectives on the artist and contextual background on her life and times.”

    “…the order of paintings didn’t jive with the audio and I had to skip all over the place to find where I was supposed to be.” (The tour is random access and some visitors still prefer a more linear tour.)

    “Every exhibit should have these!”

Quartz Composer in Leopard

Most techies probably know that Leopard has been out for a while now. Aside from all the goodness that is Time Machine, the thing that has me most excited is the new version of Quartz Composer. Create Digital Motion did a great post about what’s new, and you should read their post for the exhaustive info.

Aside from many useful things (closed loops!), there are two things that stick out to me as exceedingly useful for creating dynamic digital signage:

  • Data crunching: Quartz Composer can now load, and download XML files, which makes it much easier to move large chunks of data in and out of your composition.
  • Multiple screens — or multiple projectors: There is now support for running Quartz compositions across multiple screens, and also a cluster.

Being able to use XML data rather than just an RSS feed could be extremely useful for specifying things beyond text and images. Color values, timing, or any number of things could be included here in XML. The way we generate most of our pages here at the walker, our output is XML, so piping something like the Walker Calendar into a Quartz Composition just got much easier.

The second thing on that list is the really exciting part. As part of the Developer Tools, apple added a new application called Quartz Composer Visualizer, aka QCV. It does a couple of things. It lets you play a single quartz composition across multiple screens, which you could not do with Quartz Composer in Tiger. I’m not sure yet how this works across multiple video cards. It also adds a network mode, where a host and clients share the same composition and synchronize via the network. Here’s a movie I made of a modified version of our Vineland Lobby Kiosk Screensaver:

This is running on two different computers, my laptop and my desktop (with two displays). For the most part, the displays are in perfect sync. There is a little blip, but I think that’s probably because my Desktop is struggling to keep up, due to an older video card. There is also the option to run a second composition as an “optional processing composition”. What this means is that you can create another composition that has the logic for processing the data and settings, which gets passed along to the display compositions. Basically, this allows you to use a MVC way of doing things. Here’s a screenshot of the app in use:

Quartz Composer Visualizer

Finding clients is done via bonjour, so it is limited to the local network, but all you have to do is fire it up on each machine and they find each other. Depending on how well separate video cards are supported, it could be quite easy to run a multiple screen setup from one high-end Mac Pro, since most of QC processing happens on the video card(s). Mac minis could also work as well, though due to the underwhelming onboard video, might not have enough horsepower to do any fancy core image effects.

QCV isn’t an industrial level application; you couldn’t ship this off to a client as a complete solution for a digital signage project. But for use in house, or a situation where it could be monitored more closely, it could be extremely useful. The complete source code to QCV is also included in the developer tools, and it’s meant as a template and example for people. An enterprising objective-c developer (which I am not) could create such an industrial level application. But as a template application, it is surprisingly useful. QC and QCV are the things in leopard that excite me the most.

Two blogs that I’ve recently stumbled upon are the Open Blog at the New York Times and Alpha Channel on MSNBC. Both are blogs from the developers behind the NYT and MSNBC, respectively.

Open @ NYT Alpha Channel Twitter @ Brooklyn Musuem FFFFound!

  • Two blogs that I’ve recently stumbled upon are the Open Blog at the New York Times and Alpha Channel on MSNBC. Both are blogs from the developers behind the NYT and MSNBC, respectively. The entry on how TimeSelect was eliminated, partially powered by Amazon S3 is pretty interesting (if you like grid computing and the word terabyte), as is the entries on the redesign of MSNBC. It’s interesting to note that MSNBC and NYT have had blogs for a while, but not developer blogs. Welcome to the party, guys.
  • The Brooklyn Museum has been doing some experimenting with Twitter and it turns into a bit of a mixed bag. Is there a phone-based opportunity here? Certainly so, but Twitter doesn’t quite seem to be the right vector. Something we’ve discussed before, bluejacking the phone number of Art on Call, might be another approach.
  • Jason Kottke has an interesting post up about FFFFOUND!, which, thanks to him, is my new daily RSS post-count king. FFFFOUND! is a social image bookmarking site that has amazingly good content. Jason thinks that perhaps our curators should be looking over their shoulder:

    Among the many things that the internet has democratized is curating, a task once more or less exclusive to editors (magazine, book, and newspaper), art gallery owners, media executives (music, TV, and film), and museum curators. They choose the art you see on a museum’s wall, the shows you see on TV, the movies that get made, and the stories you read in the newspaper. The ease and low cost of publishing on the web coupled with the abundance of sample-ready media has made the curating process available to many more people.

    I don’t think curators have to worry quite yet, but it isn’t unreasonable to say that the internet has and will continue to exert influence. It also works in the other direction. Jason points out a few bloggers that have crossed over into curating gallery shows. To that list I would also add I Heart Photograph.

Opening up the social network

Building on the success of Google Gadgets (which allow developers to make small web “applets” suitable for embedding on any webpage), Google has just launched their OpenSocial API.

opensocial.pngBuilding on the success of Google Gadgets (which allow developers to make small web “applets” suitable for embedding on any webpage), Google has just launched their OpenSocial API. Basically they’ve extended the functionality of Gadgets to include code that can “talk to” participating social networks — that is, a developer now has access to the user’s profile, friend list, and much more.

This is important because it means application developers no longer have to choose which social networks they want to target. They just write their application using the JavaScript APIs provided by Google, and it will “just work” for everyone on a participating network. And it’s a big and growing list: MySpace, Orkut, LinkIn, Friendster, and – importantly – the create-your-own-social-network Ning, just to name a few. Cool stuff.

There are currently 23000 gadgets listed in the directory. After today I wonder how many of those are now in line to have some social features added and massively increase their exposure?

The Walker doesn’t have any social network apps just yet, but when we do I guarantee they will be built using this API. Maybe a Hot Or Not of contemporary art? Hmm. Or see what your friends thought of the Frida show! Or mnartists.org should copy this great idea… Could be huge!
