One of the most striking examples of censorship relates to Youtube which is also clearly tied to user generated content (of great interest to Floatingsheep). Using the Google interface one can see how access to this stream of user content has been restricted over time and space.
This is essentially one look at the flip side (location of consumption of user created content) of what Floatingsheep normally looks at (location of the production of user created content)
Some of the more striking examples are below (or play with the data yourself).
Given Canada's strong protection for personal liberty it is a good comparison to other countries. Note: all countries have some variation likely tied to normal congestion/outages on the Internet. The key is to look for big changes (i.e., drops) in the level of access. You can also compare the general level of access to Youtube between countries, e.g., compare Canada to Cuba.

CHINA: Youtube is just not an option
TUNISIA: Also blocking Youtube
CUBA: Some access but lower than Canada
PAKISTAN: Access but an effort to censor during
