Hi, thought I'd mention a few projects we've been working on using ARToolkit derivatives. These are simple projects designed to be re-purposed without coding and are free to use under ARToolkit's GPL license.
Toronto Musuem Project: futurestories.ca/toronto
Ontario Science Centre Takeaway: futurestories.ca/osc
You can make your own project by downloading the source, the .swf file is included and you can repurpose the .swf just by modifying the file playlist.xml.
Use them any way you like, post them on your website, pass them on to your friends.
Instructions on how to run the experiences on your own machine (including how to get rid of pesky Flash security errors):
Hope you like them.
