The BBC News Globe is a continuously rotating globe that displays news from two popular RSS feeds published by the BBC. As the globe rotates a new placemarker appears for each new story in the RSS feed. The concept reminds me of the concept behind the Google Earth News layer.

This is so cool.

Wow! And free!

Tracker is a free video analysis and modeling tool built on the Open Source Physics (OSP) Java framework. It is designed to be used in introductory college physics labs and lectures. Features include: 1. Object tracking with position, velocity and acceleration overlays and data. 2. Video modeling with dynamic particle overlays and data. 3. Center of mass tracking with overlays and data. 4. Rotational motion data includes theta, omega and alpha. 5. Interactive graphical vectors and vector sums. 6. Line profiles for RGB analysis of spectra and interference at any angle 7. RGB regions for time analysis of RGB data 8. Flexible video calibration options. 9. Multiple reference frame views of collisions and other motions. 10. Video filters, including brightness/contrast, ghost trails, and deinterlacing. 11. User-defined constants and variables for plotting and analysis. 12. Data analysis tool with powerful automatic and manual curve fitting. 13. Full undo/redo with multiple steps. 14. Video converter for converting edited/filtered videos to mov, gif, jpg or png formats 15. Video exporter tool for recording videos with track overlays. 16. Copy and print images of any view for use in labs and other documents. 17. Paste web or other images directly into Tracker for analysis, save if desired. 18. Helpful hints for new and occasional users. 19. Drag-n-drop trk and video files to open.

Molecular models for you to play with. You can move, rotate and resize them, change them from space-filling models into wire-frame models and back again, or simply sit back and admire the animation!

THis was shared on twitter tonight. I had seen it before, but this came at a particularly good time. Combine that with the South African billboard that Thomas Friedman points out in his talk about his book, "Hot, Flat, and Crowded" that goes like this: "German Engineering. Swiss Innovation. American Nothing!" NOW ask yourself, "Do we have time to debate this stuff (filtering policies, etc) any longer? The answer is a resounding NO!

Free samples of math games that work great on an interactive whiteboard.
