Real-time weather from paper poster

A new paper poster that knows the weather makes it easy to consult the weather report at home before you go out.

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 represents a mix of analog and digital technology.
