We did a project with some Vernier hand grip monitors (http://www.vernier.com/probes/hgh-bta.html
) that communicate with their USB device (http://www.vernier.com/go/golink.html
). We pulled the heart rate outputs into a Flash animation to create
an abstract audio/visual "orchestra" with different users' inputs.
They've held up well, and are flexible to mount because they're
wireless. Ours was a prototype for a corporate office, though, so I
can't vouch for "bullet proof" with kids around...
