Shutterstock to build "world's largest" library

Stock photo stalwart Shutterstock announced it was poised to put the Great Library of Alexandra to shame by building a brick and mortar library to house a hard copy of every one of its 250 million pictures and videos.

Shutterstock estimated its library, designed by world-renowned Belgian architect Alexandria VonPixel would be the largest in the world. Instead of librarians, the catalogue would be managed by an army of AI-powered robots called Cyanotypes.

Drones that can take your dog for a walk

The Times reported that a £200 drone had been released that can walk your dog. Called the Drone Dog Walker, the newspaper claimed the drone came with "leash control technology" to keep a firm robot-hand on unruly labradors, but warned that smaller breeds could end up literally getting carried away.

An advanced version of the drone would freeze dry your dog's poop and scoop it into a bag.

Edinburgh gets its own arial gondola to ease congestion

Scottish architecture practice ISA revealed plans to build a gondola route through Edinburgh. Called the Apex Grasshopper, the cable car would stretch from a hotel to the historic Edinburgh Castle.

ISA promised the new transport system would help ease congestion and allow visitors with only a short time in the city to make the most of their stay.

FinTech startup unveils a debit card made of lead

Chip, a FinTech startup that allows users to automatically save money digitally via an app, promised users it was bringing out a physical bank card made of lead.

Swiss Army sunglasses come with a built-in knife
