Hi again,
You have to get the cvs version for GridFlow to use the lti objects. You can find the info here : http://gridflow.ca. I have a logitech camera (quickcam 4000) that is supported by http://saillard.org. For the usb wireless adaptor I am not sure.
Once your network access is configured, you can get a lot of help to install and run pd (+ GridFlow) from irc.freenode.net, channel #dataflow.
Good luck,
Alexandre
Is there some easy installation to try out GridFlow? How hard is it to install the Fedora Core and add the planet ccrma packages, for a complete Linux beginner?
I'm on WinXP, but I have tried out PD in Linux using Pure:Dyne. The gridflow examples didn't seem to work, however... Nor did PMPD, if I remember. They just, well, didn't do anything...
I also don't know, how hard it would be to get the Logitech camera running under Linux. And to get my wireless USB running in Linux, which is the only way I can get on the internet, to download the drivers and software I might need to make everything run...

Hello David,
You could track a red led (or bright dot) in GridFlow by using [lti.SplitImageToRGB] and sending the red channel to [#motion_detect]. It outputs x and y values. I have some images of drawings made after this here : http://artengine.ca/acastonguay/projets/plotter/. You'll also find some images of early motion detection studies by the Galbraiths that puts this in perspective.
Cheers,
Alexandre

Finally, are there more advanced motion detection strategies? Like,

could I somehow put a bright red dot on my index finger, and just
detect
where my index finger is? I'd love to hear what people have done.
Alexandre Castonguay has done that a few years ago using
high-intensity
LED. I'm doing the same for my girlfriend's project, which will be presented as Café Esperanza on the 19th at 20:00.
Café Esperanza is at the corner of Saint-Viateur & Saint-Laurent, in
