Check out Teemu's blog for info on how to get started developing Python apps for your 770.

If you go to http://pymaemo.sourceforge.net/cgi-bin/moin.cgi/ you'll find the download packages. If you just want to use SSH and write scripts ON your 770, just get the one that says "runtime."

Then go back to Teemu's blog and write up the sample app. I tried it; the sample app (a simple Gtk window that you can kill) worked for me, and it was 22 lines of code.

The only downside is the runtime .deb is enormous, in terms of the 770; something like 4 megs.

I'd like to see some working PyGame examples next...
