Hi,
I enjoyed the samples once I got them going, especially the ease of use of the red drag box and the documentation.
I notices a few minor errors in the documentation that if changed might make it easier for others:
Step 4 "trackercam.config.xml" becomes "tracker.config.xml" in step 6
There is an odd backslash in step 5
Color would help in step 6
And wishful line in "Running the demo - Target Creation - Samples" - "setting this value lower will make the tracker faster but more accurate" :)
Hope this helps

re: Minor documentation errors
Thanks Chris, despite the silence at this end, your corrections were received and will go into the next release. I hope you've found the tracker useful in your projects.
cheers,
R
