rotary-movement: Fire up paint. Try to draw 5 perfect quarter circles. And 
then ditch that idea completely and forever. The only special cases where 
rotary movement works is multi-touch screens or in a limited why when your 
"mouse" is a track-ball.

Make it look like a rotary, make it usable like a slider (that is up/down  
_or_ left/right movement).

And if you really need to save space: Use it like a slider, paint it as a 
color-field with the value as number and color...

Have fun,
