[visionegg] Re: fixation viewport

Hi, Andrew and all, 

It might be a good idea to add a section to the VisionEgg web site with actual 
implemented studies (contributed by volunteers), in addition to the standard 
demos.  This would aid with some of these questions, in addition to lowering 
the bar for newbies wanting to try out VisionEgg.  At the very least, the 
addition of code templates for common psychophysical study-types, such as RSVP 
or multiple-object tracking, might be useful.

As a research programmer, I have the luxury of dedicating myself to scowering 
the related python newgroups and lists and trying things out on my own, but 
many of my psychologist colleagues don't have either the time or programming 
knowledge to do this... in effect, the very reason tools like VisionEgg exist 
(to make psychophysical studies easier to implement!)

I know I've had many of these same questions when I first started coding in 
python/VisionEgg, and I learned as everybody else does... by example.

cheers,

Hi,

the construct

screen = get_default_screen()

creates a gray screen.  The reference documentation for the screen
class indicates that it has a bgcolor parameter.  I've tried a number
of ways to set it, without success.  How do we set this parameter?  I
want, bgcolor = (0.0, 0.0, 0.0), rather than the default gray.

Best, Darren
