I did a lot of mushroom cloud explosions in Buzz Box, back in 1983/84. I liked it because it was a kind of easy way to ‘see’ the animation grow … and responded artistically to the liquid crazy shapes that strata cut makes. Not real clouds, but impressions and artistic ideas of the motion of clouds. It was a form fits function thing in my mind … this was a cool way to fit what clay extrusion animation could do, pretty easily and well … as I was first exploring the medium as an art graduate student, etc.
