ḏelta Time: Your Life in Perspective, One Tile at a Time
🎮 Play
🎯 HOOK
What if every week, month, or year of your life was a single tile on a grid, and you could color each one by how you spent it? ḏelta time turns your existence into a canvas you can actually see.
💡 ONE-SENTENCE TAKEAWAY
ḏelta time is a browser-based life visualization tool that represents your lifetime as a grid of tiles, each one a unit of time, and lets you define layers and periods to see, at a glance, how you’ve spent your years and how many you might have left.
📖 SUMMARY
ḏelta time (deltatime.life) is a creation by Sergio Basurco (chuckleplant) that landed on the front page of Hacker News in May 2026; not because it’s a product, but because it’s art.
The premise is simple: you enter your birth date, and the screen fills with a grid of tiles. Each tile is a week, month, season, or year of your life. By default, they’re colored by life stage (childhood, adolescence, young adult, mature adult). But the real power comes from layers.
How It Works
Layers are categories you define, Education, Career, Relationships, Health, Creative Work, or anything else you can imagine. Within each layer, you add periods with names, colors, and date ranges. A period might be “Studied in Berlin” under a Location layer, or “Worked at OpenAI” under a Career layer.
The result is a birds-eye view of your entire life, with color-coded strips showing how your time has been distributed across different domains. You can toggle layers on and off, zoom out to see the full span, or zoom in to weekly granularity.
The Weber-Fechner Twist
Most life visualization tools show a linear timeline. ḏelta time includes a psychophysics toggle that switches to Weber-Fechner scaling, a logarithmic perception of time that accounts for the fact that each year feels shorter relative to the life you’ve already lived. The tiles shrink as you age, matching how time actually feels. It’s unexpectedly profound.
🔍 INSIGHTS
The Medium Is the Message
ḏelta time has no server, no database, no accounts. Your data lives in the URL as a compressed query parameter. Share a link and someone sees exactly what you saw: layers, periods, colors, everything. This is a deliberate statement: the tool is ephemeral, like the time it visualizes.
The Mature Adult Paradox
One of the app’s life stages is “mature adult”, spanning from roughly 30 to 60. Seeing this block as a single undifferentiated chunk of 30 years is a quiet gut punch. It asks: what are you doing with those decades?
The Author’s Intent
“Once you take a look at your life in perspective, my hope is that you’ll close your browser and touch some grass. It’s not a product. It’s art. It’s your life.”

💬 QUOTES
“Time is precious. It’s so you get a birds eye view of how you’ve spent your time, and decide how to spend it next.”
- chuckleplant
“I like the use of the Weber-Fechner law, that’s a lens I use to think of age as well. The idea is that experienced time is proportional to log time, i.e. it’s why time seems to move faster as we age.”
- Hacker News commenter
“Are you still alive?” dropdown is diabolical."

⚡ APPLICATIONS
For Personal Reflection
Spend 10 minutes mapping your life into layers. The act of defining periods forces you to confront how you’ve allocated your most finite resource. Most people discover imbalances they intuitively knew about but never saw laid out visually.
For Life Planning
Use it forward-looking: set your expected lifespan and see how many tiles remain. Then define layers for what you want your future periods to look like. It turns abstract goal-setting into a visual budgeting exercise.
For Conversations
Share your timeline with a friend or partner. It’s a surprisingly effective way to communicate your life story without a linear monologue. The visual format invites questions and discovery.
For Existential Occasion
Sometimes you need a quiet moment with your own mortality. ḏelta time provides that space without being morbid about it. The dark green theme and clean typography keep it contemplative rather than alarming.
- Pitfall to Avoid
It can be emotionally intense, especially with the Weber-Fechner view. If you’re in a fragile headspace, the visual compression of your remaining tiles might hit harder than expected. The author acknowledges this; it’s art, not a wellness app.
⚠️ NOTES
- WebGL required: the tile rendering uses WebGL, so older machines or certain browsers may not display the grid
- Mobile works: tested on mobile, though the concentric view is more practical on larger screens
- No data persistence: refresh without a share URL and your layers are gone (by design)
- Color blind?: the palette is customizable per period, so you can choose distinguishable colors
- Open source: the source is available (check the page source for the minified bundle)
