Having finally created a twitter account, and ‘following’ some IRL and online contacts, I was introduced to the  Flowing Data via a link from one of the tweets. The whole site looks fascinating but the self-surveillance category has some really interesting posts, including:

• one on AntiMap – an open-source tool set that allows you to record your movements, post-process them and then play them back.
• Tracking mouse activity on your computer
• What you do online is data

From a GI S&T perspective, all of these self-surveillance tools are likely to be of interest in one way or another.

From a cartographic perspective, the post “Van Gogh for the colorblind” talks about research that applied various colour filters to Van Gogh’s paintings which highlights the importance of picking colours wisely and thinking about how your maps and diagrams look to others. A link to an online tool by  Kazunori Asada that allows you to apply three colour vision types to your own images.
