One note of caution- on the few ‘notebook’ (small) cams I’ve tried, the ir blocker is actually ‘painted’ on the lens and has to be polished off or removed with chemicals.  Much harder to deal with than a separate ir blockers the larger cams have, IMO.

I have not tried the creative you listed above, but thought I would pass this along as a general caveat.

good point!
I ran across this the other day on the net; sounds interesting, albeit expensive: http://exilim.casio.com/browse_cameras/exilim_pro/EX-F1/specifications
anyone know what fields per second means? casio clearly states fields instead of the frames in fps for a specific resolution.

EDIT: as found on wikipedia: Digital video cameras come in two different image capture formats: interlaced and progressive scan. Interlaced cameras record the image in alternating sets of lines: the odd-numbered lines are scanned, and then the even-numbered lines are scanned, then the odd-numbered lines are scanned again, and so on. One set of odd or even lines is referred to as a “field”, and a consecutive pairing of two fields of opposite parity is called a frame.

i used a smilar kinda (specs wise) logitect cam for a fiducial based project earlier… two issues i faced ... most probaly the cam lens is painted with the IR filtering paint… so no luck trying to remove that...and you can really remove the lens and fit another one there ... (i might be wrong here)… secondly..having a higres cam doesnt really help unless u have it running on a quad core or something cause the heavier / hi-res image from the cam actually adds to the latency since it takes loonger to process… my bet 640X480 to 960X720 is a goos resolution for upto 60” screens.... so maybe look for a good 30 fps firewire cam at 640 X 480 ..

I’m trying to look for a good cam to use, I currently had an ezonics usb ii, probably the crapiest webcam I could find in my box-o-junk. I’m interested in a 720i/p cam that is not firewire, but does the image processing on it’s chips, and simply sends the video via usb. I am hoping for a higher res so writing could be a possibility. Jeff han’s original debut board had .1” accuracy and 50hz refresh, which leads me to believe it could have been a european ccd cam. that accuracy sounds high though. I’m shooting for 50-60hz/fps and a good res, but I am using a laptop with no firewire/firei port. I do suppose I could get an adapter, but would like to lower the amount of extra stuff that is needed.
I did get a handheld cam corder to pass video into my computer with a pinnacle usb converter i had, though the converter is forced to run at ntsc or pal (under 30fps each). Any ideas?

after some research, I found this: http://damien.douxchamps.net/ieee1394/cameras/
all firewire cameras since 1999 to 2008 it seems, with most specs
