Flyer for the 1992 Rollins Band tour of Melbourne, Australia 

I saw the Rollins Band for the first time as a teenager in 1992. I went to the afternoon all-ages show. The show was mesmerising. Pulverising. No strobes. No coloured lights. Just the band. The Rollins Band, grinding out a sonic-fury under white work-lights. I kept the flyer.


Kollum is a concept for a collaborative location-based realtime audio experience that takes place in urban or suburban environments. Kollum is an attempt to conceptualise and capture the elements of location-based audio experiences that incorporate elevation or altitude through cumulative and persistant columns of sound. Users can use the audio recording features of their smart phone or mobile device to create a new audio block that makes up a column at their location  or add an audio block  to an existing column nearby.

This animation is an attempt to visually represent the assembly of a number of sound columns in a urban space (Does not represent actual experience…YET!).

In the absence of Glass

Working out the concept for the rig with a pen, post-it and highlighters.

In the absence of my own Google Glass, I’d like some type of wearable rig that can hold a mobile device such as a tablet or mobile phone. This rig would sit on the wearers shoulder or be strapped to their chest. It would allow the wearer to view any assistive augment displayed on the screen of the mobile device and also allow the wearer to use both hands to interact with the point of interest. The rig would need to be able to be adjusted to suit the wearer and multiple types of devices to prevent a confronting experience if the mobile device was placed too close to the users face.

Come to think it, this rig may not be practical for use in confined spaces or actually anything at all. It’s not very immediate or portable. Reject.

Sew, grow and mow: An AR lawn art experience

Cubist lawn art.

Sew, grow and mow is a multi-user virtual lawn art experience played in real locations with real dimensions in real time. Sew, grow and mow is a continuation of an existing idea about persistently augmenting a space.

The experience

Users choose a location nearby or a location they can easily access to place their virtual lawn. Suitable locations can be determined by browsing satellite photographs such as Google maps. They can then choose the design.

Users can choose from a library of lawn art design templates or create their own with a basic lawn art editor. Lawn art designs can be previewed by going to the location and viewing the proposed design through Sew, mow and grow or by previewing their design superimposed on an aerial photograph such as Google maps.

Users can then choose the grass (native to their area or imported) they’d like to sew for their lawn. Each type of grass has a particular quality such as shape, colour, speed of growth, resistance to drought and climate that can enhance and contribute in some way to the finished lawn art. Users have the option to review their location, design and sewing choices before they can start to grow their lawn. They can also choose the climate they’d like for their lawn. Climate can be based on location of lawn or from a weather data supplied by an agency such as the Bureau of Meteorology.

Once the climate has been selected the users can then start growing their lawn. Grass can take a long time to grow. That’s why Sew, grow and mow has a feature to expand and contract time. Doing this enables the user to grow their lawn in a short period of time. Users can check the growth of their lawn by going to the location of the lawn and then viewing the lawn through Sew, mow and grow or by viewing their virtual lawn superimposed on a satellite photograph such as Google maps.

Users can start shaping their lawn art once the lawn has grown to a minimum or recommended length suitable for mowing. Users need to go to their location and then choose from a lawn mower, hedge trimmer or mini-trimmer. Holding their device like a lawn mower, hedge trimmer or mini trimmer, users can use Sew, grow and mow to view their virtual lawn and move around their location to start shaping their lawn art. A stencil of the users design will be placed over the screen to help the user shape their lawn art. The completed lawn art can be shared with friends, removed completely or maintained for as long as the user wants to. Mistakes or errors in mowing can be repair by returning to the Grow stage.

The following diagram describes the experience of Sew, grow and mow.
