I was musing about something similar a week or two ago. Perhaps a colorless,
stringy, almost slimy, viscoelastic polymer with the same IOR as soapy water
could be gently woven into a loose mesh...
Bonus points if this material is non-toxic (preferably a food product), and only
metastable so that no trace of it remains after the bubble bursts.

Gorgeous and nice choice of music too.

Oh yes! I love it.
I am not sure, sometimes in soap bubbles you can see the iridescence
swirl round (especially before bursting iirc). Have you included that in
your animation? I seem to see some swirling...

Thanks, Thomas :)
I didn't animate the irid but I did animate the blob components such that each
sphere slowly rotates on its local axes by some random amount before being
translated into position each frame; so the irid pattern does change on each -
some much faster than others.
The whole scene is basically just this:
//------------------------------------------------------------------------------
// Bubbles
//------------------------------------------------------------------------------
#declare M_Bubble = material {
texture {
pigment { srgbt 0.99 }
finish {
diffuse 0
reflection { 0.05, 1 fresnel on }
specular 0.99 roughness 0.001
conserve_energy
irid { 0.3
thickness 0.25
turbulence 1.2
}
}
}
interior { ior 1.001 }
}
#declare MAX = 512;
#declare aScale1 = array[MAX];
#declare aScale2 = array[MAX];
#declare aRotate1 = array[MAX];
#declare aRotate2 = array[MAX];
#declare aRotate3 = array[MAX];
#declare aTrans1 = array[MAX];
#declare aTrans2 = array[MAX];
#local n=0;
#while (n < MAX)
#declare aScale1[n] = RRand(0.9, 1.1, R);
#declare aScale2[n] = RRand(0.4, 0.7, R);
#declare aRotate1[n] = <rand(R)*360,rand(R)*360,rand(R)*360>;
#declare aRotate2[n] = <rand(R)*360,rand(R)*360,rand(R)*360>;
#declare aRotate3[n] = RRand(30,90,R);
#declare aTrans1[n] = <RRand(-20,20,R),RRand(-10,10,R),RRand(-20,20,R)>;
#declare aTrans2[n] = RRand(-15,-20,R);
#local n=n+1;
#end
blob {
threshold 0.2
#local n=0;
#while (n < MAX)
sphere { 0, 1, 1
scale x*aScale1[n]
scale aScale2[n]
rotate aRotate1[n]
rotate aRotate2[n]*clock
translate aTrans1[n]
translate y*12
rotate y*aRotate3[n]*clock
translate <0, aTrans2[n]*clock, 10>
}
#local n=n+1;
#end
material { M_Bubble }
}
Cheers

Thanks Stephen, these bubbles have been a lot of fun.

Okay, I couldn't help myself, I simply /had/ to do it. So, I traced all of
Lucy's verts (stored in a massive array) outward onto a sphere. As the animation
progresses each vert morphs back into original position giving a Bubble->Lucy
transformation.
The video is here: https://vimeo.com/47055835
That was fun :)

That was great! Good work indeed. Make the video a bit longer at the end
though; it is cut off too abruptly ;-)

Very nice. Agree with Thomas, she needs to drift a little longer to be properly
appreciated!
