An anniversary gift that grows every year
Most anniversary gifts mark the moment and stop there. A Cosmic Echo transmission does something different: it keeps going. The signal you send today is still moving through space on your 5th anniversary, your 20th, your 50th — always further, always faster than anything you've built on Earth.
That's the nature of electromagnetic radiation in a vacuum: it never stops. Your anniversary message will be traveling through space long after the restaurant closes, long after the flowers dry, long after the photo frame is moved to a different wall. The signal is permanent in a way that no physical object can be.
For couples who value what is real — what is verifiable, what actually happened — there is nothing more authentic than a radio wave that left Earth the day you marked another year together.

The annual transmission tradition
Some couples use Cosmic Echo as an annual tradition — one transmission per anniversary, building a series of signals moving through space at different distances.
Year 1: 1 light-year out. Year 5: 5 light-years — already past the nearest stars. Year 10: 10 light-years, reaching Epsilon Eridani and other Sun-like stars in that range. Year 25: 25 light-years, approaching Vega.
Each Signal Tracker page becomes a chapter — the distance counter showing how far that year's message has traveled. Collected together, they form a kind of cosmic record of the relationship: a time-lapse of a love story told in light-years.
The framed certificate from your first transmission. The digital links for every year after. A tradition that keeps growing as long as you do.

What to write for your anniversary
Anniversary messages tend to fall into a few categories. All of them work.
What this year was: "Year [X]. We renovated the kitchen, changed jobs, argued about nothing and everything, and somehow ended up stronger. Here is what I know about us that I didn't know last year."
What you're looking forward to: "This is what I want for the next [X] years: more of this. More mornings like the ones we've had. More decisions we make wrong and figure out together. More ordinary Tuesdays."
A love letter: "I have been trying to find the words for [X] years. Here is what I have: I choose you. I would choose you in every version of everything. This message will travel through the universe for millions of years. I want it to know that."
The honest one: "We've been together [X] years. It hasn't always been easy. It has always been worth it. That's not nothing. That's everything."

Anniversary-specific destination ideas
Some destinations pair beautifully with specific anniversaries:
1st anniversary — Alpha Centauri — 4.37 light-years. Your message reaches the nearest star system in 4.37 years — a milestone within the relationship's own future. Something to look forward to together.
25th anniversary — Vega — 25 light-years. A beautiful coincidence: a 25-year message heading to a 25-light-year star. Vega is one of the brightest stars in the summer sky, visible without a telescope.
Any anniversary — Polaris — The North Star, 433 light-years away. The star that guides travelers home. For a couple who have become each other's home.
Any anniversary — Deep Space — No specific destination. Your love radiates outward in all directions, indefinitely. Some couples find this the most honest choice: love doesn't have a target, it just goes.

The framed certificate in your home
The framed anniversary certificate ($89) is a museum-quality piece designed to live in your home. Dark background, minimal typography, your message exactly as transmitted — alongside the destination, transmission date, station, frequency, and the cryptographic hash that makes it permanently verifiable.
It goes on the bedroom wall, the living room, the office. It's the kind of thing visitors notice and ask about. And the story — a real radio signal carrying your anniversary message, aimed at a specific star, traveling at the speed of light — is a story worth telling.
The printed certificate ($49) is equally beautiful without the frame, perfect for placing in a memory box or presenting as a gift. The digital certificate ($19) arrives instantly — the Signal Tracker link is the gift, and they can watch the distance counter from anywhere in the world.
