Pulled by donkey, the container consisted of four LCD screens, powered by solar panels.

It was a mobile roadshow, starting with music to draw a crowd and then switching to a three-minute film on the biggest of the screens.

While the topic - digital literacy - was not the most entertaining, it was engaging for the audience, many of whom had never seen a screen or moving images before.

After the film, the audience was invited to use smaller touchscreen tablets to answer a series of questions about what they had seen. 

There were prizes of T-shirts and caps for those with the highest scores. 

For those who couldn't read, the questions were posed in diagram form.
