TOKYO: Ever have a yen to be a sumo wrestler? Curious to see how you might look bulked up like a behemoth and with a traditional wrestler's topknot? Now, an iPhone app can show you – and without even packing on any kilos. The “SumoBooth” app, developed by Tokyo-based MotionPortrait Inc, a subsidiary of the Internet-linked So-net Entertainment Corp , allows users to upload a photo of their face taken with their phone. The images are processed to add pounds and the wrestlers' trademark hairstyle with a topknot. The app will also record voices and alter them to give users a sumo wrestler's distinctive husky sound. “We do a lot of apps involving faces – we have one with zombies – and we thought that turning people into sumo wrestlers would be kind of fun,” said Masaharu Yoshimori, chief planning officer at the company, which offers the app for 115 yen ($1.41). – Agence France
