Therdthanawa Kanama, a student from Maha Sarakham province, won hands down in Thailand's first Doodle 4 Google competition.
The 15-year-old boy, from Sathit Maha Sarakham School, beat more than 46,000 other submissions with his doodle of a Royal Barge.
The doodle will be visible on the Google Thailand homepage for 24 hours on Her Majesty the Queen's birthday on August 12.
Therdthanawa said the royal barge Suphannahongse, which serves His Majesty the King in various royal ceremonies, was his inspiration.
The image of the barge's reflection exemplifies the value of traditional craftsmanship, culture and history, he said, adding that he had used the colour gold because it stood for prosperity.
Michael Lopez, a Google doodler and judge for the competition, said he was delighted to see the work of talented young students who imbued their doodles with everything that was unique and beautiful about the Kingdom.
"Therdthanawa stood out because of his creative use of the colour gold and the image of the royal boat, which symbolises Thai craftsmanship and displays his respect for tradition. I can't wait to see it on the Google.co.th site in August," he said.
Apart from his doodle making it to the Google homepage, Therdthanawa has also won a Bt25,000 scholarship, a new laptop and an all-expenses-paid trip to Googleplex in Mountain View, California with his teacher and a parent. He will also meet Google's doodle team and see how they regularly create images.
The Doodle 4 Google competition in Thailand was organised by Google in cooperation with the Education Ministry and Thailand Knowledge Park's children's museum. Participants aged five to 18 were told to give the Google logo a unique look under the theme of "My Thailand".
