Blowing in the (fetid subway) wind

A quick post today: I’m at the airport gate waiting to get on a plane.

I sent out a tweet about this brilliant advertising application of the Pi last week, but so many of you missed it on Twitter and have emailed to tell me about it since then (including one Dr Eben Upton) that I thought it deserved a spot here. Here’s a digital billboard that responds to the wind created by an approaching train.

The advertising agency behind this piece of clever is Åkestam Holst from Sweden, working with production company Stopp for Apotek Hjärtat’s Apolosophy products. Stopp says the ad was scheduled to be run for one day only, but it was so popular that the company which owns the screens asked for it to run for the rest of the week “as a way for them to show the opportunities their screens can offer”. When you think about it, a device like the Pi that can run a full HD digital display and can be hooked up to respond to real-world inputs is ideal for this sort of setup. These guys aren’t the only agency to be using a Raspberry Pi behind digital displays: but this is the best integrated use of the device I’ve seen in this context, and it’s made for a very powerful piece of advertising.
