In unusual but true stories this week, we have a bag-connected airport-floor tent, the world's smallest view camera, the first self-drive aerotaxi, and a golfer who lost sight but continues to play.

All the odd and interesting anecdotes from around the world are here in our review.

Bag-connected airport-floor tent

If you're a world traveller, then you've probably experienced it – a several-hour airport layover where you'd like to get some sleep, but without the added complication or cost of going to a hotel. That's where the Trollaby comes in, as it serves as a sort of bag-connected airport-floor tent.

Invented by Austrian entrepreneur Marc Brugger, the Trollaby takes its name from the words "trolley" (as in a wheeled carry-on suitcase) and "lullaby". When not in use, it packs down into a flat rectangular bag that's about the size of a laptop computer.

The user can then make a nest out of their jacket, sweater or whatnot, or they can simply lay out an optional inflatable mattress. There shouldn't be much of a risk of theft from their suitcase as they zone out, as its fasteners are located right by their head.
