The billboard knew how hot it was.

McDonald's Qatar launched two new Sprite mixes for the summer: Passionfruit mixed with Sprite, and Watermelon mixed with Sprite. The plan was a full out-of-home takeover across Doha, nine venues, both languages, on every screen format the city runs.

The brand handed us one thing to start from. A single layered PSD. Everything that happened next, the motion, the live data and the build, was ours.

In a Qatar summer, the most honest thing a cold drink can do is admit how hot it is outside. So we let the ad say the temperature out loud.

The creative reads the real feels-like temperature, turns it into a live "Thirst Score," and then cuts it to zero. Forty-five degrees of heat, dropped to FEELS LIKE 0°C, straight into the ice-cold Sprite mix.

We pulled every layer out of the file: fruit cutouts, ice, sparkles, type, mascots, and rebuilt the whole thing as animated HTML. No exported video files, no per-frame baking. Just code that plays frame-perfect on whatever screen the city throws at it, in English and Arabic.

The creative is not a video of the idea. It is the idea, running live.

Each panel runs the same five-beat story, and the first three beats are filled in by the weather, the moment it loads.

The live part is quiet by design. A Cloudflare Worker wakes up on a schedule, reads the weather for every venue, computes the Thirst Score, and writes it all into one tiny cached file. The creatives just read that file when they load.

So the screens never wait on an API, the data never goes stale mid-loop, and every panel across the city shows the same live number at the same time.

Roadside LED, mall portrait panels, vertical poles, ultrawide screens. Same master design, adapted cleanly to every ratio, in both languages, with the live layer wired into all of them.

The unlock was never one good frame. It was building the creative and the software as a single thing, so what used to take a studio weeks shipped from one platform in days.
