I'm working on a demo on real-time visualization and I'm trying to think out of the box. Looks like any big data real-time demo is on twitter or traffic data. Are there any other options out there that publish real-time data (for free)?
Thanks

Healthcare: Wearable devices are an example of real-time analytics which can track a human's health statistics. For example, real-time data provides information like a person's heartbeat, and these immediate updates can be used to save lives and even predict ailments in advance.
Real-time data (RTD) is information that is delivered immediately after collection. There is no delay in the timeliness of the information provided. Real-time data is often used for navigation or tracking.
A real-time analytics platform enables organizations to make the most out of real-time data by helping them to extract the valuable information and trends from it. Such platforms help in measuring data from the business point of view in real time, further making the best use of data.
Just some thoughts:
As stated by the other comment, have a look to weather, forecast (or similar services).
What about data from the Universe?
Here's some real time flight tracking data: the evaluation plan is limited but free.
Twitter Streaming API, Facebook RealTime Updates API (in case you hyave already an app on the social Network), Foursquare
Various energy production (real-time and quasi real-time) data.
On these ones probably you have to fiddle around the pages to track the sources of the data, sorry.
Google Analytics RealTime API (for your registered websites)
Bitcoin transactions, Stock Market API
And here and here an "not-so-updated" list of other Real-Time API services (some free, some others not).
