I discovered this site a week or so ago... they pay .00005 Bitocoins for each page that you view for 30 seconds, and .0001 Bitcoins for each video you watch (the videos vary in length... usually between 2 and 5 minutes). They don't offer very many webpages to view on any given day (usually 4 or 5), but the videos seem to be unlimited and you can build up A LOT of Bitcoins going back each day (they maintain a balance for you). The site is in Spanish or something, so keep Google Translate handy (unless you know Spanish).
