That page has some interesting examples.  Here's something similar to
the Polyrhythm one done in Chuck and LiCK

polyrhythm.ck:

class Pattern extends FloatProcedure
{
    dur step;
    float freq;
    float pan;
    SinOsc sin;

    fun void connect()
    {
        sin => Echo e => Pan2 p => dac;
        0.2::second => e.delay;
        pan => p.pan;
        freq => sin.freq;
        0.0 => sin.gain;
    }

    fun void run(float value)
    {
        0.5 => sin.gain;
        step => now;
        0.0 => sin.gain;
    }
}

Pattern right;
0.25::second => right.step;
440 => right.freq;
0.5 => right.pan;
right.connect();

Pattern left;
1::second / 6 => left.step;
330 => left.freq;
-0.5 => left.pan;
left.connect();

spork ~ Loops.loop(right, right.step, 18::second).run();
spork ~ Loops.loopN(Loops.loop(left, left.step, 16::second), 0::ms,
2::second, 1).run();

10::second => now;
<<<"done">>>;


The loop methods are

loop(FloatProcedure, wait between procedure calls, total length of time to loop)

and

loopN(Procedure, wait between procedure calls, initial offset, number
of times to loop)
