Example

root =
    l 0 FILL : ss 400 bouquet

quality = 1000

bouquet =
    r 36 (ss 1.3 flower5)
    : r 15 flower6

flower6 =
    demiflower6
    : flip 90 demiflower6

flower5 =
    demiflower5
    : flip 90 demiflower5

demiflower6 =
    collect (
        for i in 0..12
            r (i * 30) (petal6 quality))

demiflower5 =
    collect (
        for i in 0..5
            r (i * 72) (petal5 quality))

petal5 i =
    if i == 0
        EMPTY
    else
        s 1 0.0001 SQUARE
        : ss 0.005 (tx -0.5 (l 0 CIRCLE))
        : tx 0.5 (r 144.04 (ss 0.998 (tx 0.5 (lshift (1 / quality * 0.6) (petal5 (i - 1))))))

petal6 i =
    if i == 0
        EMPTY
    else
        s 1 0.0001 SQUARE
        : tx -0.5 (ss 0.01 (l 0 CIRCLE))
        : tx 0.5 (r 120.21 (ss 0.996 (tx 0.5 (lshift (1 / quality) (petal6 (i - 1))))))
