ah nice :)


I see a: "Extensions: GL_EXT_geometry_shader4" in my List. This is
probably what you need.

GEM information
OpenGL info
Vendor: NVIDIA Corporation
Renderer: GeForce 9800 GT/PCI/SSE2
Version: 3.3.0

And it should look like this, if you own a nvidia-GPU. Otherwise you
will have to install the proprietary drivers.
