Tech Know: Giant 'Etch-A-Sketch' toy at FutureEverything
A giant electronic copy of an Etch-A-Sketch toy is among innovations on display at Manchester's FutureEverything festival.
Project A Sketch is designed by the city's MadLab, a group of inventors who run technological amateur design schemes.
The fair also includes motors that "swarm" around empty Victorian swimming baths.
Ellie Gibson has sampled FutureEverything's delights.
