That looks like a nice source for classical graphics, but I fear that it will
have a limited readience because of the language (Disclaimer: I am not working
for Time Magazine, my French is acceptable, and we drink their wine. ).

Even reading such stuff in German is difficult for me, because of the required 
switching between computer terms and translation.

For lattice, show.settings() is a good starter. Too bad it's miles from showing
the complete set of options. No student around looking for the first steps to 
fame?
