In stories this week, we have a paper poster updating the weather in real time, artwork made from used telephone keyboards, the world's first fully automated toilet for dogs, rings and accessories created using human teeth, and an ingenious rotating indoor garden that saves space.

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

Real-time weather from paper poster

A paper poster that knows the weather has been launched.

It's not a particularly detailed forecast -- just a single icon of whether to expect rain, clouds or sun at 8 am, 12 pm, 4 pm and 8 pm.

The screen is a traditional paper poster, which uses heat-sensitive ink to "light up" the relevant icons using forecast data pulled from the internet. It is a mix of analog and digital technology.
