What app would a durian seller find most useful?
According to Mohd Syahmi Iman Mohd Shahril, 10, that would be Food Panda, "to deliver food to him, and maybe deliver durian to others".
He and eight other pupils in Montfort Junior School's Picasso's Pals Club have, over the last few weeks, been giving freelance illustrator Quek Hong Shin's sketches of 50 locals - an SG50 project - a "telecommunications" twist.
The boys chose their favourites from Mr Quek's drawings and matched the characters, including a young getai singer and a female beer promoter at a coffeeshop, with the apps they thought would be the most apt for their lifestyles.
Ten-year-old Howard Sim, for instance, was inspired by Mr Quek's drawing of a girl with lavender-coloured hair.
In his imagination, she would be using YouTube, Musical.ly, Snapchat, WhatsApp - "all the social media apps... because she's very trendy".
"This project was very interesting because we can try to make (the characters) our own by adding other details," he said.
A fortnight ago, the pupils' teacher, Mrs Amy Khoo, 47, also invited Mr Quek, 36, to drop in. "I wanted the children to meet a real artist because many of the children have the misconception that, if you want to be an artist, you have no future," she said.
Their work, among others from the school, will go on show at Cheng San Public Library, in Hougang Mall, from Sept 3 to 12 .
