On Friday October 4, 2013, a collective action was held to post some of the ST1500 action eyes all along Lleida. A group of volunteers was able to post more than a thousand eyes on the streets in just a couple of hours.
Enric from Trevol.tv did a fantastic video documenting this guerrilla action. You can see it just below. Thank you very much to all those volunteers and specially to Enric.
