hi,
every destination angle is also (angle - 360), then you just compare the
absolute values, if it is shorter to go from 10 to 270 (which is 260
degrees) or 10 to -90 (which is -100).
useful objects might be "abs", "mod", <, >, <=... and maybe you will also
need "moses" or min/max for handling the line object..

If I use "line" I have my angle go from 0-90-180-270 Clock wise when I want
it to go 10-0-270 Counter clockwise. The line object does work, but only
when the angles differ by less than 180 degrees. So the question is how do I
make a patch which tweens the angle by the shortnest distance?
