London, England (CNN) -- Less than six months after joining Twitter, Marc MacKenzie has found his groove -- starting with a cliche and then giving it a twist.
And the talent has paid off. One of his tweets was dubbed the world's most beautiful by British actor and ardent Twitter fan Stephen Fry at the Hay Literary Festival in Wales this weekend.
"Stephen Fry likes my material -- how cool is that?" MacKenzie said Monday.
The winning tweet was: "I believe we can build a better world! Of course, it'll take a whole lot of rock, water & dirt. Also, not sure where to put it".
It was one of dozens MacKenzie, a medical physicist from Canada, submitted to the contest.
"I actually submitted 35 tweets, but mostly because I found it so hard to choose -- they're hit and miss, but sometimes I'm pretty proud of what I've written, and I find it hard to pick a favorite," he told CNN.
He's gone from about 150 followers at twitter.com/marcmack to more than 1,000 since the prize was announced by Fry, who has more than 1.5 million followers.
He has modest hopes for how his success will change his life, he said.
