I have spent the last few hours getting acquainted with G-Force, and I must say that for the money this is a real bargain. If my math is correct, there are over 10 million different combinations as I figure, which makes this the most worthwhile investment I have ever seen for a computer. GO G-FORCE! You guys rock.... And the screensaver is absolutely boss, on top of the music visuals. Unbelievable, fantastic, cool, etc..... Thanks Guys!
