Campus Party, one of the Spanish-speaking world's largest technology conferences came to Colombia first in 2008. It has been replicated ever since with growing successes and the Rising Voices grantee Hiperbarrio  community in Colombia has been actively participating in these events with enthusiasm (2008 , 2009 ).
Deisy Alvarez in Hiperbarrio blog reflects  [es] about the impact of Campus party in their lives:
Since 2008, the year in which they conducted the first campus party Colombia, it has become well established in what it is today, an event which is not only national but international, and that from its inception it has become a center for conversion work, collaborative experiences and it is also clear that it is the biggest technology festival in the country.
Therefore we have implemented a “give to receive” approach, which means each person transfers his or her learning to an individual who does not have this knowledge in areas such as campus blog, development, free software and more.
Today I reflect and conclude that in CAMPUS PARTY technology is not about only human relations, information sharing, or a monetary value [..] it is a friendship that is generated from what others think. [machine translation]
The proposal was to use the pin hole camera technique to record the activities of CampusBlog among others.
Now what is a pin hole camera?
A pinhole camera is a simple camera without a lens and with a single small aperture — effectively a light-proof box with a small hole in one side. Light from a scene passes through this single point and projects an inverted image on the opposite side of the box. (Wikipedia )
Franky Posada explains [es] in a three part video how to build a pin hole camera:
You can watch more pictures taken in this technique from the Hiperbarrio Flickr page .
Apparently this technology has created a sensation in the community. So HiperBarrio started arranging workshops  [es] on Pin hole photography for its citizen media projects.
Some HiperBarrio members wrote about their experiences in the Campus party. Henry El Sucio wrote about  the talks and lectures given in Campus party, especially learning about Creative Commons License and its implication in using others contents such as texts, images etc.
Yeskenia writes  in Convergentes blog:
Campus Party Colombia, is a digital event in which many people around the country gather with guests from other regions to share knowledge. In the 2010 version new areas were introduced that did not exist in the minds of the previous Campus parties: Innovation, Creativity, Security and Networks.
I'm impressed and also the group of HiperBarrio was also impressed to learn that in the field of astronomy it became practical and easy to handle the tools required and we should not be “Astronomers” to develop satellites and learn to observe the sky. [machine translation]
