Exactly.
What I originally had in mind when I thought about this syntax was something
like :
[in a media block...]
warp
{
turbulence .75+.1*sin(5*clock)
scale .9+.2*sin(7*clock+3)
translate <.1*cos(11*clock+5), clock, .1*sin(13*clock+7)>
}
warp
{
turbulence .75+.1*sin(13*clock+5)
scale .75+.15*sin(17*clock+7)
translate <.1*cos(5*clock+11), -clock, .1*sin(7*clock+13)>
}
[...]
