Quartz Composer and Revolution

[Andre Garzia]

Brent,

while I think it's terribly easy to make quartz composer compositions  
(is this how we're supposed to call them?) access the iSight or any  
videosource, and apply effects to it, I think we have no methods for  
picking that and saving to a file. I think it all happens in runtime  
and that you can't pick your videograbbing + effects and save for  
example the last 10 minutes of interaction so that we can replay it  
later. But quartz composer is cool for making screen savers that  
present real world data in creative ways, for example displaying  
computer sensor data and mails, or getting news feeds from the tubes  
and eye-candy-ing them into nice things.

If you ever find a way to record what is being played so that we can  
replay it later, please post this here for I'd really use that.
PS: happy compositions for you!

thanks
andre
