I finally decided to buy Pukka. I kept trying it out, and not quite deciding to buy it. But two things happened today that made up my mind.

One was I discovered that as well as being fantastic for posting to del.icio.us, it also gives me access to all my del.icio.us bookmarks, organised by tag!  By adding this to the Mac status bar at the top of the screen it gives me quick access to my del.icio.us bookmarks.

The other was reading the post in Justin Miller’s blog (the creator of Pukka) about “The Price of Free” which discusses the reluctance of people to pay for utility programs.  Pukka was discussed favourably on a podcast, but the announcer was saying it should be free, not shareware.

I realised that $14.95USD (which was $16.27AUD) was a reasonable price for the time Pukka will save me and it will encourage me to make better use of del.icio.us.  And hopefully paying for it will encourage Justin and others like him to keep providing great applications.

Frank Van Ham is from the IBM Research - IBM’s Many Eyes project. Focussed on the collaborative aspects of information visualisation - the communication of ideas by sharing visualisations.

He describes the history of the project saying that the idea for it came from a variety of things they were noticing as researchers, but in particular three projects.

1. The first project was done by a colleague - a Visual representation of peoples email done in 2003. She stressed privacy to people - but found that people actually sent screenshots to other people - didn’t want to keep it private they wanted to share it.
2. The second project was the Baby Name Voyager. A graph of the popularity of baby names over the last 100 years. In 2005. People started challenging each other to find patterns in this data, as a game.
3. In 2004 there was a visualisation of the USA election with red states and blue states. Different visualisations were shared through blogs.

From these examples they developed their research agenda of “Massive Public Visualization”. Scaling the audience instead of the volume of data.

Important part was to make it easy for people to comment on the data and make their own visualisations. People get excited when they can see their own data.

The site is available www.manyeyes.com

They provide a wide range of visualisation types. Types of uses that they have seen of the site:

• Scientists have been using it for analysis.
• Other people have been using it for personal expression.
• Journalism and Advocacy
• Social Interaction

ManyEyes lets people take their visualisations and embed them into their own websites or blogs. The site is free, but all data is visible to everyone.

Another video from the see conference #3

Zachary Lieberman, Peformance Artist and Researcher speaks on “Making the invisible visible”.

He starts his session with a demonstration of piece called “Manual Input Session“. That uses a camera looking down on an overhead project with a red screen on it. As he makes shapes with his hands and other objects the computer generates shapes and sounds.

Was a fine artist, got into computers because he liked animation and liked the idea of bringing things to life.

He likes the works that he does not to be focused on technology, wants them to be something happening without needing to understand the technology.

Until he was invited to give this talk he hadn’t thought of himself as being involved in information visualisation. But after thinking he realised that a lot of his work is doing something similar. He is trying to make sense of data - the human body, gesture, the voice and come up with a reasonable visualisation.

He has been involved in developing Open Frameworks a C++ library which is also used for visualisation (not released yet).

He is excited and passionate about making the voice visible.

Created both performance pieces (Messa di Voce) and interactive installations exploring ways to see the voice. Went on to adapt some of the technology developed for these for schools teaching children with learning disabilities.

Developed open source software for choreography - rotoSketch - that lets you draw simple lines over video of a dancer and visualise the choreography.

He showed a work called ‘drawn’ that was used both for performance and installation where you start by making an ink drawing and then can move the pieces of the picture around on a screen. Sounds are generated by the shapes and movements.

He concludes by saying his research is about trying to create wonder, to create a sense of wonder for the people who see his work.
