Most people mark a milestone birthday with a dinner. Imran Zainal marked turning 50 by writing a message the size of a small country across the map of Klang Valley. The corporate trainer and TEDx speaker spent 12 days, from August 26 to September 7, driving and walking routes that spelled out a giant greeting when traced on a GPS map: "Happy Msia Day. Create As 1. And Rise." The finished artwork covers 1,230 square kilometres — bigger than Singapore — and was timed to finish for Malaysia Day.

The final image looks clean, but getting there was anything but. Around 85 per cent of the route was done by car; the rest had to be walked, including the fine details inside the letters — the wings of a dove, the petals of a hibiscus flower drawn near Kajang. That meant trudging through overgrown Chinese cemeteries in Kajang and Klang, where Imran came out covered in thorns and, by his own account, blood. In Cheras, his planned line ran straight through an active construction site. Rather than break the shape, he talked his way past the safety officer and wore a hard hat to record the data. Outdated map data and unexpected roadblocks forced constant improvisation.

The project also nearly collapsed at the start. Imran originally worked with a partner, but his perfectionism — redoing lines that were slightly off — ended the collaboration, and a month of recorded data was lost with it. With the Malaysia Day deadline looming, he started over alone, which he later decided was fitting: a message about unity, written by one stubborn person. The route ended at KL Tower, where he invited his hiking and life coaching students — Malaysian, Japanese and Chinese youths among them — to complete the final 50 metres of the letter 'S', a deliberate passing of the baton to the next generation.

There's a personal backstory too. In the late 1990s Imran researched a script in Oxford's libraries before abandoning creative work for the corporate world. Turning 50 made him question whether a "second act" was possible, and the GPS artwork was his answer. Next up: a map-sized silhouette of Malaysia's first prime minister, Tunku Abdul Rahman.

Why should a traveller care? Because Klang Valley — the sprawl around Kuala Lumpur that most visitors just pass through on the way to the Petronas Towers — turns out to be full of hidden texture: quiet cemetery hills in Kajang and Klang, residential backstreets in Cheras, hill roads near KL Tower. Imran's project is a reminder that even a notoriously congested metro area rewards slow exploration, and that you can see the place with fresh eyes simply by tracing your own route and looking at the map afterwards. It's also a good excuse to visit: Malaysia Day falls on September 16, and the capital celebrates with events, food and a noticeably festive mood.
