[PD] Can pd+gem can do this?

[vibronik at laposte.net]

Hi all,

i got a project in mind, and i´m looking for a tool capable of doing
this:

i got a camera, that feeds 320x240 at a quite fast rate (100fps)

The image will be black and white and show points moving (a hundred,
think about fireflies, i´d the same)

The idea is to map and track those points, and display in realtime
moving sprites with gem (like smileys, or anything)

So, i digged a bit, and found either pd+gem or reactable software
framework+custom code

Any advices, testimonials would be great!

Thanks a lot

Tristan
