Yes, I'm very interested. I found Mapnik some time before, but I've not
really understood for what mapnik is good. The tutorials seems broken.

My current attempt is to access postgis direct without an additional
library. But if Mapnik eases this task I'm open for it.

Is there a minimal example to draw some OSM data in a window with
Mapnik and e.g. OpenGL?
