Great demo: fun, absorbing and a nice aesthetic too. If I get some time 
I might try to write a foxes/rabbits or simple genetics simulator.

That's good to know.  Having a quick glance at the wx code helped turn 
up a bug - I realised the docs for Wx::Brush are cut off. A custom brush 
is created thus:

Wx::Brush.new(Wx::Colour.new(r, g, b), Wx::SOLID)

The second argument is the fill style - other options are things like 
Wx::CROSS_HATCH. Brushes that stipple Bitmaps can also be used to create 
textures.

http://www.wxwidgets.org/manuals/2.8/wx_wxbrush.html

The simplest constructor should be:

Wx::Brush.new(Wx::Colour(r, g, b)

But this form was missing - now added to SVN for the next release.
