Subject: Re: Webcam as a light sensor.

I found this http://rubydoc.info/gems/camcapture/0.3.0/frames
but I can't install it. Typing "gem install rb_webcam" in RubyGems 
Package Manager didn't work.

"You also did not write what this has to do with ruby."
I just need method to check if light is on or off. Simple binary state.

I found one website controlled by flicking your light switch and I 
wanted to make a game which use this feature. For example - game like 
VVVVVVV where if light is on - gravity is applied to floor and if there 
is dark - gravity is applied to ceiling. I'm pretty sure it can be made 
easier in Flash or something, but it would be too much effort to 
learning whole new language and/or graphic/sound library (I'm using ruby 
with GOSU now).
