Hill Making

A Chinese landscape painting in grey, with a glowing green rock at its centre

A piled stone hill that feels with you.

Classical gardens, biosensing and generated sound and light.

As a child, a stone hill in the park was my favourite place.

I wandered up and down the rocks, through high platforms and caves, getting lost and then suddenly finding my way. For the old garden owners, who walked their gardens alone, these hills were where feelings could be let out.

Each of five spaces, from points and lines to frames and a finished form

I broke the hills down into five kinds of space.

Cave, gorge, cliffside, tunnel and platform, joined by a graph of my own: planar, undirected, sometimes cyclic, weighted by length. I tested it on several famous hills.

The stone’s parts laid out, and an exploded diagram with a pulse sensor, LED ring, conductor plate and Arduino

A stone you touch reads how you feel.

Inside the Sensus Stone, GSR and PPG sensors on an Arduino measure your skin and pulse, and a small model sorts the signal into burnout, stress, calmness or stimulation.

Each feeling answers with a piece of a landscape painting.

Each feeling calls up its element as generated visuals and music around you: TouchDesigner for the images, ChatGPT and Stable Audio for the sound.

A storyboard: visitors touch the stones, and two strangers end up talking

Strangers in the same cave hear each other.

When two visitors touch the stones, their music and visuals overlap. A space that once held one person’s feelings becomes a way to meet.
