Chimes of T-Bank

On the eve of the New Year 2026, a tower with large screens could be seen on the streets of Izhevsk and Novosibirsk. It was not just a countdown, but a digital representation: chimes struck every hour, festive balloons flew across the screen, and then the wishes of the city's residents appeared. This interactive installation was an initiative of T-Bank, and M-Social was responsible for the digital implementation.

How It Worked: From QR Code to Animation

 

Every day from 1:00 PM to 9:00 PM, a digital script unfolded on the tower's four screens:

  • Two screens displayed a QR code leading to a wish-making form.
  • The other two showed stylized clocks that triggered an animation every hour: the chimes striking, flying balloons, snowflakes, and the call "Time to make a wish."

Wishes submitted through the form were moderated, and T-Bank employees uploaded them via a special Telegram bot. Starting at 2:00 PM, these wishes began to appear on the screens—one after another, displaying names and text in neat tiles. And at 9:00 PM, the system would animatedly announce the winner whose wish would be granted.

 

The Technologies Bringing the Screens to Life

 

For smooth animation and uninterrupted content updates, we used the following technology stack:

  • Backend: PHP, Backpack, PostgreSQL
  • Frontend: React + Next.js
  • Animations: Lottie library

Special attention was paid to integration with third-party software for broadcasting to the physical screens—this helped avoid delays and maintain image clarity.

 

A Closed Data Channel: How the Bot Worked

 

The Telegram bot served as a secure channel for content upload:

  • It accepted Excel files (.xlsx) with two columns: "Name" and "Wish".
  • Assigned a unique ID to each file.
  • Accumulated data without overwriting or deleting history.
  • Worked only for employees on a whitelist.

This ensured the smooth operation of the entire chain—from collecting wishes to displaying them on the big screen.

 

Result: Technology as a Conduit for Emotions

 

Thanks to a well-tuned animation system, precise data upload via the bot, and optimized integration, the project ran seamlessly throughout the holiday season. T-Bank not only created bright New Year's decorations for the cities but also fulfilled the winners' wishes.

The "T-Bank Chimes" project proved that technology can create real magic. When the chimes struck in the evening city and someone's wish appeared on the screen—the digital product became a part of the holiday and human emotions.
