Ceramic, Phase Change Material (PCM), Thermochromic, Photochromic and Photoluminescent pigments.

22C is a collaboration with Joan Barrass (Ceramics) and Linda Davy (Everything !) designed for the Embracing Innovation 4 exhibition opening July 24 at Crafts ACT in Canberra.



This thermodynamic ceramic vessel is a heat battery that has been designed for the climate in Canberra. The vessel contains 2 litres of inorganic salt solution known as a Phase Change Material (PCM) that acts as a concentrated heat mass when it changes from solid to liquid at 22C.

The surface is coated in thermo-chromic pigments chosen to indicate the state of the PCM inside it. On cold winter mornings the blue surface indicates the inside is solid. As it warms up it turns yellow to indicate the inside is melting.

At the end of a sunny day the white surface indicates the inside is liquid. In the evening when the temperature drops below 22C the surface turns back to yellow and then blue again as it solidifies and releases stored heat.

When sunlight falls on the surface a pattern of photo-chromic purple rings indicate that the solar input is charging up the thermal battery. At night the surface glows purple with photo-luminescent pigments to indicate stored energy is being released.

Embracing Innovation Vol. 4, the fourth instalment of the Centre’s Embracing Innovation exhibition series, presents the work of craft practitioners and designer makers who have embraced cutting edge technologies into their practices. A selected group exhibition comprising six individual artist and two collaborations Embracing Innovation Vol. 4 will present work from artists and researchers from leading Australian and international research and academic institutions.

Tuning Fork and Variations



Tuning Fork and Variations

The tuning fork rules the orchestra through its precisely repeatable production of a tone at a specific frequency. The shape is designed to produce a simple tone, and slow-motion video shows how the two-pronged arrangement amplifies the primary mode of vibration while damping other more complex twisting and flexing modes. The variations on the tuning fork in this exhibition reconfigure the arrangement of the prongs to allow unruly vibrations. Could an unruly tuning fork sound interesting enough to join the orchestra too?

The exploration of the space of variations is facilitated by Computer Aided Design and 3D printing.

These Tuning Forks are part of the Unruly Orchestrations exhibition at Belconnen Arts Centre in Canberra from 13-29 June 2014.

ARTyMotion Competition


The Hypertension Singing Bowl was runner up in the inaugural SportsCare and Physiotherapy ARTyMOTION Exhibition. The theme for the exhibition is HEALTHY MOVEMENT. All mediums may enter.


Hypertension is on view in Sportscare Offices around Canberra throughout 2014. We look forward to the further development of the relationship between art and sport in ARTyMotion 2014.

Experience and Evaluation in the Collective Creation of a Public Digital Exhibition

Experience and Evaluation in the Collective Creation of a Public Digital Exhibition describes the collaborative creation of a public digitaFrontCover-hiresl media exhibition located outdoors in the Garden of Australian Dreams at the National Museum of Australia. The exhibition was created on the ABC Pool site where people share media and work on projects. Over one hundred collaborators pro-duced in excess of 700 images, texts and sounds for the exhibition within two weeks. The rapid production of so much content raised the need to scale formative evaluation to match production. Crowd curation was undertaken through online comments, and through nominating or flagging items as favourites on the ABC Pool site. The location of the exhibition outdoors raised usability and technical issues, that included visibility, distraction, GPS accuracy and download delays. The project was analysed using the Experience and Evaluation Framework proposed in this volume. This analysis led to the identification of additional elements that further generalise the framework to projects that involve collective creativity, out-door exhibitions, mobile media, and public digital art.

Interactive Experience in the Digital Age explores diverse ways of creating and evaluating interactive digital art through the eyes of the practitioners who are embedding evaluation in their creative process as a way of revealing and enhancing their practice. It draws on research methods from other disciplines such as interaction design, human-computer interaction and practice-based research, and adapts them to develop new strategies and techniques for how we reflect upon and assess value in the creation and experience of interactive art.

Produsage of Transmedia Storyworlds

BookCoverTransmedia Practice: A Collective Approach positions transmedia as a dynamic phenomenon which undergoes constant innovation as it absorbs current trends and advances in its constituent disciplines.

My chapter describes 3 experiments in the peer production of transmedia storyworlds with 100+ students in Crossmedia Production at the University of Canberra in 2011, 2012 and 2013.

Making Things Growl, Purr and Sing

Mozzi is a sound synthesiser that allows the Arduino to purr, growl and sing, instead of just buzzing the way it usually does….purrgrowlsing_800

Mozzi lets you create all sorts of sounds on the Arduino using familiar synthesis units including oscillators, samples, delays, filters and envelopes. These sounds can be embedded in clothing, appliances, sports equipment, gadgets, toys, installations, and many other places where sound not been possible before. Check out contributed examples in the Gallery http://sensorium.github.io/Mozzi/gallery/

Who’d have thought

Who’Hypertension+Me+beanied Have Thought is a blog about design innovation and creative reinvention where Jane and Will interview artists and designers with questions that focus on up-cycling in the creative arts.
Jane’s interview about the Hypertension Singing Bowl led me to think about 3D printing as a way to up-cycle waste metals. The organizers of the first e-Waste Academy described the “Age of Urban Mining” in which precious metals and rare earth minerals are mined from the growing deposits of electronic junk that contain 50 times the amount of gold and precious metals than ores mined from the ground.
Shapeways.com  recently announced the dawning of a “New Bronze Age” with the introduction of the capability to 3D print CAD designed objects in Bronze and Brass. Singing bowls and gongs were invented in the Bronze Age due to the malleability and musical properties of these metals.
What if discarded mobile phones could be up-cycled as singing bowls through urban mining in the new bronze age?
