A desk lamp that helps you breathe.

A wood-and-glass lamp that doubles as a guided breathing exercise. Hands on the base, and the light pulses to slow your breath: no app, no screen.

§ 01 Problem stillness at the desk

Anxiety is loudest where students spend most of their time, at the desk.

Anxiety is loudest at the desk. The funnel came from where anxiety shows up in young adults' lives, and the techniques that consistently top the list for managing it.

Brief 00

Mental health

A broad start, sharpened by post-pandemic anxiety.

Step 01

Student anxiety

Gen Z is the most anxious generation on record.

Step 02

Studying as the peak

Anxiety peaks while studying, and the desk is where it lands.

Step 03

Breathing as a tool

Breathing exercises rank top alongside physical exercise.

63%
of US students report increased anxiety post-COVID (APA)
62%
of UK students report peak anxiety while studying
#2
most-recommended stress-relief technique, second only to exercise
§ 02 Concept two modes, one lamp

A desk lamp that pulses when you need a moment.

Ilia works like a normal desk lamp until you place your hands on its wooden base. Two modes let the user choose how much initiative it takes.

The breathing cycle
5s inhale Light brightens slowly.
5s exhale Light dims slowly.
2 minutes later Light turns yellow; keep going or let go.
Mode 01

Free.

The lamp stays out of the way, available whenever wanted, never when not.

For users who already know when they need a break.
Mode 02

Timed.

Every two hours, the light turns blue and waits, resetting only after a full two-minute cycle.

For users who lose track of time and would otherwise never stop.

Switch modes with a rear potentiometer.

§ 03 Making glass, wood, hands

A cloud on a wooden dome.

The form had to feel warm, calm, and tactile: something a stressed student would want on their desk.

Two columns of form ideation sketches: organic cloud-like glass diffuser shapes on the left in pencil, and rendered wooden base form studies on the right
Form studies: glass diffusers, base profiles.
Form

A cloud, diffused.

An organic, slightly random glass shape, not a perfect dome: calmer, more atmospheric.

Base

Wood, warm to the touch.

The base is what users place their hands on. Wood invites contact in a way plastic or metal wouldn't.

Sizes

Two bases, two hand sizes.

Testing showed no single size worked for everyone. Both shipped, with slightly different necks.

From furnace to finished pair.

Glass made first with Ingrid in the hot workshop, then cold-worked and sandblasted. Wood glued from MDF blocks, then turned on the lathe by technicians as we assisted.

Hot glass being blown and shaped with wooden rods to create the cloud-form diffuser
01 Glass blowing Sphere blown, neck shaped with jacks, rods pressed in for the cloud creases.
The blown glass cooled in the annealer, then sawn at the neck and sandblasted to a frosted finish
02 Cold work Cooled in the annealer, neck sawn to length, sandblasted to a frosted finish.
MDF blocks glued together and clamped overnight, then mounted on the lathe for woodturning
03 Wood prep MDF blocks glued overnight, turned on the lathe by technicians to a dome.
The wooden base hollowed out with a drill and chisel, electronics fitted inside, glass diffuser seated on top
04 Assembly Base hollowed with drill and chisel, channels cut for the LDRs, glass seated on top.
The remake

We made the glass first, then found it too small for the bases. The base couldn't shrink, it needed room for electronics. We remade four glasses with deeper creases, and picked the best two.

§ 04 Electronics light sensing light

Sensing hands by the shadow they cast.

LDRs (light-dependent resistors) on the base detect hands covering them. Proximity and touch sensors were considered, but LDRs stayed discreet and the team had already coded with them.

The Ilia electronics laid out: Arduino Uno, NeoPixel ring, two LDR sensors with soldered wire extensions, a potentiometer, and an external power switch, all on a breadboard during testing
The full electronics.
  1. 01

    Arduino Uno

    Runs the code, drives the NeoPixel animation, reads sensor input. Lives inside the hollowed base.

  2. 02

    Two LDR sensors

    Soldered to wire extensions on opposite sides. When hands cover both, ambient light drops and the cycle starts.

  3. 03

    NeoPixel ring

    An 8-pixel ring in the glass diffuser: yellow default glow, soft pulsing blue during a cycle.

  4. 04

    Potentiometer

    Located at the back. Switches between Free and Timed.

  5. 05

    External switch

    A USB inline switch cuts power directly, simpler than a soft on/off and saves power when idle.

The hard part of the code

Pulsing the LED smoothly needed a sine function, beyond what we'd learned. Our tutor Matthew helped with the maths so the animation actually breathed, not stepped.

§ 05 Testing on real desks

Tested where it would actually live.

Quick studio sessions with first-time users, then a longer context test: one student, one full day at her desk.

What landed
Worked

Intuitive without instructions: "the right balance between interesting and basic enough to fit my space."

Worked

The two-size split resolved naturally: bigger hands, bigger base. Two right sizes, not one ideal.

What didn't
Didn't

No markings around the potentiometer made mode-switching unclear. Easy fix: an engraved knob.

Didn't

One tester with severe anxiety noted continuous touch could trigger sensory overload, a real question for contact-required interactions.

§ 06 Final outcome the pair, glowing
