Don’t worry you won’t fall in. This is the “Eco Sign” for you, a digital manhole cover that harnesses the rainwater to power it. Tap a foot left or right and it gives you instant info on the nearest train station or bus stop. Maps and signboards be damned! A multifunctional manhole with a rocking display…and all the thieves vying for it!
