If you havn't asked yet, try the gtk2-c and gtk2-perl maillists. Remember, Goo is still in early developmental stages...and probably needs alot of efficiency improvements.....but it's tough to get the author to do it for free. :-( Me? Just flying by,.....thoughts?... if you think about the problem for a few months, you probably can come up with some hack to make it faster, like using shared memory segments to hold the common data, then use threads to manipulate the grid data. But to be honest, this stuff probably should be written with the c version of the Goo library. Perl tacks on alot of baggage on the math calculations needed.

But that is what is great about Gtk2, you can prototype in Perl, then rewrite in c......the gtk2-c tutorials are very easy to understand, especially now that you know Perl/Gtk2.
