Another one of the awesome tools that hydra offers is a set of modulators. I can't really explain very well what they're exactly doing,... but I can show you:

speed = .33  
osc(10, [.2, -.4, .04].smooth(0.05), [0, Math.PI/2].smooth(.1)) .colorama([0.005,0.33,0.66,1.0].smooth(1)) 
.luma(.3, .3) 
.posterize(7) 
.modulateRepeat(osc([3,13].fast(.5)).rotate(Math.PI/2)) 
.out()
