12-Year-Old Boy Builds Simple Lego Creation At Kids' Exhibit, Becomes Internet Hero

He has even been described as a 'conceptual artist'.

A 12-year-old boy has been hailed a hero after a photo of his Lego creation went viral.

Joel Willans, from Finland, tweeted a photo of some kids’ competition entries during a Lego exhibit on Sunday 30 July. 

Next to much larger creations - including a multi-level ship and what looked like a robot with legs - was 12-year-old Riley’s worm.

A single yellow Lego block.

“Riley, you’re a genius”, Willans tweeted.

In less than a day, the photo has had more than 70,000 retweets and 155,00 likes.

Twitter users replied with their astonishment at Riley’s “genius” creation - some even referring to him as a “conceptual artist”.
