Or is that too boring? <snip> A calculator is definitely not too boring -- and potentially very good tutorial material. That is, it runs all the way from REPL use ("(+ 5 7)", "(pow 2 100)") to GUI programming. For lists etc., you can do parsing of algebraic input or polynomial calculation. Think emacs calc. As for C integration, you could try libfftw (the Fastest Fourier Transform in the West) or try to find some application that could use a calculator added to it. I think gnumeric and the other various gnomish spreadsheets already use Guile. Or perhaps gnuplot could use a new language... Anyway, I think a new tutorial on "how to use Guile" would be great --- I used the two tiny little examples in the manual for a long time. Andrew
