linear(time, 0, 5, 0, 100);

put that in for something like a rotation value and it'll rotate from zero to 100 degrees over five seconds. Now just replace 100 with an expression control slider and throw a wiggle on it and the rotation will still approach 100 but will wiggle around the current value the whole way. The possibilities are endless.
