In Dougie Wallace’s photos of Mumbai taxis, the chatter, yelling, and constant horns of the city are almost audible. A selection of his images is on show at Gayfield Creative Spaces, Edinburgh, as part of the Retina photography festival until 30 July. For four years, the Glasgow-born Wallace focused his photos on one kind of taxi in particular: the Premier Padmini, a 1960s workhorse painted in black and yellow. Locally known as “Kaali-Peeli”, there were once more than 60,000 of them in the Indian city. But thanks to laws restricting pollution, the cars now are fast disappearing from Mumbai’s streets.

When you think of the People's Liberation Army, you probably don't think of line dancing. But the Chinese military's latest online recruiting video makes a soldier's life look more fun than the macarena. The brief spot, posted last week on the website of the Ministry of National Defense and going viral, features tanks and fighter jets, as well as soldiers dancing in rows to a quirky hit tune by the Chopsticks Brothers called “Little Apple”. Its lyrics include, “You are my little dear little apple/I can never stop loving you”.

Makers, meet your DIY dream car. Toyota‘s Calty Design Research Studio just unveiled its brand new Urban Utility concept car – an ultra flexible vehicle with a transforming interior designed to meet the needs of today’s on-the-go makers. Toyota packed an amazing amount of space into a footprint the size of a compact car. The U-squared can seat up to four passengers, or you can fold down three seats and roll out an array of racks, movable rails, and storage trays that can accommodate everything from surfboards and bikes to bulky equipment (like your homemade tesla coil).
