Twinkle, twinkle, little star

I've been more in the mood for snippets with effects rather than even a small project.

Here are some simple stars in the sky for a background.

Here is a still but they do twinkle if you run this.

function setup()
    st = {}
    ns = 100 -- number of stars
    for i = 1,ns do
        if math.random(2) == 1 then g = .25 else g = -.25 end
        l = 5 + (math.random(39)/4)
        st[i] = {g=g,l=l,x=math.random(WIDTH),y=math.random(HEIGHT)}
    end
end

function draw()
    rect(0,0,1,1)
    background(20, 46, 181, 255)
    strokeWidth(3)
    lineCapMode(SQUARE)
    stroke(255, 255, 255, 255)
    fill(255, 255, 255, 255)
    for i = 1,ns do
        if st[i].l <= 5 and math.random(2) == 1 then st[i].g = .25
        elseif st[i].l >= 15 and math.random(2) == 1 then st[i].g = -.25 end
        st[i].l = st[i].l + st[i].g 
        ll = (15 - st[i].l)/2
        line(st[i].x-st[i].l,st[i].y,st[i].x+st[i].l,st[i].y)

        ellipse(st[i].x,st[i].y,6,6)

Nice shading on those blocks

Nice! Would be better if it has Twinkle Stars song as the music background.
