Btw:
on January 14th-18th, in Calgary, was the first use of GridFlow in a theatre play, actually an interdisciplinary production incorporating elements of dance, poetry, gymnastics, short film, and actor-controlled display of pictures.
Ken Campbell, in Ottawa, designed and constructed the wireless emitters/receivers/sensors, that were used by the three actors at chosen moments during the play.
I designed the patches to decode sensor informations and process the visuals, and handled the equipment during the shows.
Artengine (http://artengine.ca/) generously provided some equipment and funding.
[My next plan is to present a tape of this show at the next meeting of Montréal PureData Users Group, possibly accompanied with talks by several involved people.]
