@kali66 yeah, I just thought the broken glass looked like spider web. Funny how, when I gave you the prompt, my mind had moved away from violence and was thinking about humor, as in "that kid's antics are such a riot" and confusion as in a "riot of color". But this image is actually more in line with the original impulse!
@francoise i had the other two interpretations in my mind too, just didnt find anything suitable, relieved to have something, i dont like to leave a challenge undone. :)
