Earlier this year Austrian television broadcast a 30min documentary about Plan Ceibal which was made by Julieta Rudich, an Austro-Uruguayan journalist and film maker. Thanks to a tweet by Plan Ceibal's Miguel Brechner I now found out that an English version of the documentary is available on YouTube.
I think it is very well done indeed and probably one of the best videos anybody has made about Plan Ceibal and the real impact of OLPC. Definitely well worth watching!
Note: As the video isn't embeddable clicking on the image will direct you to its YouTube page.
