Help !! Alter blinkMcylon setting over time!!

Need help and guidance to alter blinkMCylon setting over time. Like having the cylon go faster the more time passes. So when it starts i goes really slow and you more time passes it speeds up.

Im also interested in changing the values of the r, g, b, over time. Like when it starts the cylon is full red after 1 min its all green and after another minut its all blue.
And changing the delay of the "BlinkM_fadeToRGB ( blinkm_addr, r,g,b);
delay(50);"

also maybee changing the fade speed as the time passes as well.

All ideas are welcome

thanks to Tod and a great forum.
