I'm a programmer(ish)

Ben advised that I get my toes wet in programming with Context Free , so that's what I did. I made this video. My program read:

startshape second

rule second{
10 * {x .1 y .1 r 40} vortex {}
second {y 0.2 rotate -0.3 size .995}
}

rule vortex{
CIRCLE {s 0.8 h 104.89 sat 0.9083 b 0.7459}
vortex {y 0.1 r -3.75 s .995 h 0.5}
}
