mem - I apologise if I caused offence. I wasn't trying to suggest that the servo library isn't used, just that I haven't used it, but do use servo's, and I/we felt a slower movement might be interesting.
More preciously, the feeling was based on some movie CGI effects where several movements are co-ordinated to simultaneously arrive at a single common goal, rather than be governed by the rate of each servo. The angle+duration thought was my simple way to get the effect. I haven't built any working examples, so I am happy to play with this off-line until we do.
I also feel 'bloating' the standard libraries, with features which very few have a need for, reduces the quality of the Arduino platform for the vast majority (especially when the code is Open Source). So I am happy to hack the code to satisfy a need, but I wasn't expecting the hacks would necessarily go into the main development line.
Okay?
