Quicksilver

Touch is input.
Behavior is output.

A finite set of reflective pools rests on a white working surface.

The premise

What if information were a material you could manipulate with your hands?

Pull one pool into two. Push two together. Draw a connection. Break it. Draw a boundary around a group.

The physical action already expresses the intent.

You change it.
It changes back.

Touch

The same material carries both sides of the conversation.

Your touch changes its topology. A connection can be drawn directly between two things without opening a tool, choosing a mode or describing the relationship.

Two pools are joined by a thin surface-level connection beneath a fingertip.
Touch is input.

Then take your hands away.

A small vocabulary
Pull apart.
Push together.
Draw a connection.
Break it.
Draw a boundary.
Gather it all up.

Trace

Run a finger through the material and leave a temporary trace. Name something. Divide it. Teach it a relationship.

A fingertip leaves a temporary trace through a smooth reflective material.

The material can remember what happened without displaying every interaction forever.

Belong together

A connection says these relate.

A boundary says these belong together.

The same pools before and after a thin boundary groups them together.

No legend is required. The relationship is spatial.

Behavior

Now stop touching it.

Quicksilver can gather, separate and reorganize itself. A connection may reappear. Two things may drift toward each other. Something inside a group may resist staying there.

A small set of pools begins to establish relationships without a hand present.
Behavior is output.
Information that can organize itself.

Morphable

Quicksilver isn't mercury. It is an imagined computational material whose defining quality is viscosity.

Fluid enough to think.
Viscous enough to hold a thought.

Fluid, it can flow and reorganize. More viscous, it can stretch, divide, hold relationships and be picked up like putty.

Press it against something and lift it away.

Capture this.

Press it somewhere else.

Put this here.

No upload button. No selection rectangle. Touch the thing you mean.

Graspable

The information can be complex. The material should remain graspable.

Keep the working set small enough to gather in your hands. Pull it apart when you need distinctions. Bring it back together when you don't.

When you're finished, gather the pieces back together.

Quicksilver is material that thinks back.

Not a liquid-metal visualization. A shared input and output medium: you express intent by manipulating it, and computation answers through the behavior of the same material.
